Cytokine

Background

Oncostatin M (OSM) is a multifunctional cytokine that belongs to the Interleukin-6 subfamily. Among the family members, OSM is most closely related to leukemia inhibitory factor (LIF) and it in fact utilizes the LIF receptor in addition to its specific receptor in the human. A biologically active OSM receptor has been previously described that consists of a heterodimer of leukemia inhibitory factor receptor (LIFR) and gp130. OSM is synthesized by stimulated T-cells and monocytes. The effects of OSM on endothelial cells suggest a pro-inflammatory role for OSM and endothelial cells possess a large number of OSM receptors. Recombinant human OSM (209a.a.) has approximately 43% and 42% amino acid sequence identity with rat and murine OSM.

保存条件:
-20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以首次配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项:
由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。

Cytokine

Background

Leukemia inhibitory factor (LIF) is a member of Interleukin 6 family. This protein is mainly expressed in the trophectoderm of the developing embryo, with its receptor LIFR expressed throughout the inner cell mass. LIF has the capacity to induce terminal differentiation in leukemic cells. Its activities include the induction of hematopoietic differentiation in normal and myeloid leukemia cells, the induction of neuronal cell differentiation, and the stimulation of acute-phase protein synthesis in hepatocytes. LIF is used in mouse embryonic stem cell culture, because that removal of LIF pushes stem cells toward differentiation, but they retain their proliferative potential or pluripotency. It is also used in phase II clinical trial, which can assist embryo implantation in women who have failed to become pregnant despite assisted reproductive technologies (ART). Mature human LIF (180a.a.) shares 78%, 82%, 91%, 88% and 87%a.a. sequence identity with mouse, rat, canine, bovine, and porcine LIF, respectively.

Cytokine

Background

CD40 ligand is a 261 amino acid type II transmembrane glycoprotein belonging to the TNF family and can be cleaved into two chains: the CD40 ligand membrane form and CD40 ligand soluble form. It is primarily expressed on activated CD4+ T lymphocytes, and also found in other types of cells, like NK cells, mast cells, basophils and eosinophils. In total CD40 ligand has three binding partners: CD40, α5β1 integrin and αIIbβ3. It mediates a range of activities on B cells including induction of activation-associated surface antigen, entry into cell cycle, isotype switching and Ig secretion and memory generation. CD40-CD40L interaction also plays important roles in monocyte activation and dendritic cell maturation.

Category

Cytokine

Background

Flt3-ligand (FL) is a recently identified hematopoietic cytokine whose activities are mediated by binding to the transmembrane glycoprotein Flt3. Flt3 was first discovered as a member of the class III subfamily of receptor tyrosine kinases (RTK) whose expression among hematopoietic cells was found to be restricted to highly enriched stem/progenitor cell populations. Additionally, class III RTKs include the receptors from SCF, M-CSF and PDGF. Not surprisingly, Flt3-ligand is also structurally related to M-CSF and SCF. All three cytokines have been shown to exist both as type I transmembrane proteins and as soluble proteins. The predominant human FL isoform is a transmembrane protein that can undergo proteolytic cleavage to generate a soluble form of the protein. An alternatively-spliced FL mRNA, encoding a soluble form of the human FL, has also been identified. FL is widely expressed in various human and mouse tissues. At the amino acid sequence level, human and mouse FL are approximately 72% identical and the two proteins exhibit cross-species activity. FL has been shown to synergize with a wide variety of hematopoietic cytokines to stimulate the growth and differentiation of early hematopoietic progenitors.

Cytokine

Background

B Cell Activating Factor Receptor (BAFF-R), also named tumor necrosis factor receptor superfamily member 13C, is a member of the TNFR superfamily. It is highly expressed in spleen, lymph node, and resting B cells and to some extent in activated B cells, resting CD4+ cells and peripheral blood leukocytes. BAFF receptor is a type III transmembrane protein containing a single extracellular phenylalanine-rich domain and binds with high specificity to BAFF (TNFSF13B). It enhances B-cell survival in vitro and is a regulator of the peripheral B-cell population. BAFF receptor/BAFF signaling plays a critical role in B cell survival and maturation.

Background

B-cell activating factor (BAFF), also known as Blys, TALL-1, TNAK, and zTNF4, is a TNF ligand superfamily member and has been designated TNFSF13B. Produced by macrophages, dendritic cells, and T lymphocytes, BAFF promotes the survival of B cells and is essential for B cell maturation. BAFF binds to three TNF receptor superfamily members: B-cell maturation antigen (BCMA/TNFRSF17), transmembrane activator and calcium-modulator and cyclophilin ligand interactor (TACI/TNFRSF13B) and BAFF receptor (BAFF R/BR3/TNFRSF 13C). These receptors are type III transmembrane proteins that lack a signal peptide. Whereas TACI and BCMA bind BAFF and another TNF superfamily ligand, APRIL (a proliferation-inducing ligand), BAFF R selectively binds BAFF. The BAFF R extracellular domain lacks the TNF receptor canonical cysteine-rich domain (CRD) and contains only a partial CRD with four cysteine residues. Human and mouse BAFF R share 56%a.a. sequence identity. BAFF R is highly expressed in spleen, lymph node and resting B cells. It is also expressed at lower levels in activated B cell, in resting CD4+ T cells, in thymus and peripheral blood leukocytes.

Cytokine

Background

TNF-beta, also known as lymphotoxin-alpha (LTalpha) and TNF-alpha are two structurally and functionally related proteins that bind to the same cell surface receptors (TNF RI and TNF RII) and produce a vast range of similar, but not identical effects. Mature TNF-beta/LTalpha and TNF-alpha share approximately 35% protein sequence homology, and the biologically active secreted forms of both proteins are trimers. Human and mouse TNF-beta/LTalpha share approximately 74% homology in their amino acid sequence and exhibit cross-species activity. Soluble TNF-beta/LTalpha is a homotrimer in solution. Secreted TNFbeta/LTalpha also complexes with the membrane associated LTbeta/TNFSF3 to generate two types of heterotrimers, LTalpha1/beta2 and LTalpha2/beta1.

Cytokine

Background

The clinical use of the potent antitumor activity of TNF-α has been limited by the proinflammatory side effects including fever, dose-limiting hypotension, hepatotoxicity, intravascular thrombosis, and hemorrhage. Designing clinically applicable TNF-αmutants with low systemic toxicity has been an intense pharmacological interest. Human TNF-α, which binds to the murine TNF-R55 but not to the murine TNF-R75, exhibits retained antitumor activity and reduced systemic toxicity in mice compared with murine TNF-α, which binds to both murine TNF receptors. Based on these results, many TNF-α mutants that selectively bind to TNF-R55 have been designed. These mutants displayed cytotoxic activities on tumor cell lines in vitro, and exhibited lower systemic toxicity in vivo.

Cytokine

Background

Tumor necrosis factor alpha (TNF-α), also called cachectin, is the best-know member of the TNF-family, which can cause cell death. This protein is produced by neutrophils, activated lymphocytes, macrophages, NK cells, LAK cells, astrocytes endothelial cells, smooth muscle cells and some transformed cells. TNF-α occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally-occurring form of TNF-α is glycosylated, but non-glycosylated recombinant TNF-α has comparable biological activity. The biologically active native form of TNF-α is reportedly a trimer. Human and murine TNF-α show approximately 79% homology at the amino acid level and cross-reactivity between the two species. Two types of receptors for TNF-α have been described and virtually all cell types studied show the presence of one or both of these receptor types.

产品简介(Background)
Recombinant Human TNF-α contains soluble cytokines (77-233aa) of the protein. This protein was expressed in E.coli and purified without tag. It is expressed as soluble trimer, which has been validated by Size-exclusion chromatography. Apoptosis induced experiments confirmed that the protein had high biological activity.
TNF-α is a multifunctional proinflammatory cytokine that belongs to the tumor necrosis factor (TNF) superfamily，and it produced by various immune cells, including T cells, B cells, natural killer cells and macrophages. As a transmembrane protein, TNF-α’s membrane-bound site can be cleaved by the metalloprotease ADAM17/TACE, releasing the soluble cytokine into the extracellular space to form polymers [1-2]. The cellular response to TNF-α is mediated through the receptors TNFR1 and TNFR2. TNFR1 can be activated by both the membrane-bound and soluble trimeric forms of TNF-α, and resulting the downstream apoptosis signaling pathway. While the TNFR2 responds to the membrane-bound form of TNF-α, and promotes T cell activation and proliferation [3]. TNF-α plays a key regulatory role in inflammation and host defense against bacterial infection. The role of TNF-α in autoimmunity is underscored by blocking TNF-α action to treat rheumatoid arthritis and Crohn’s disease.

本产品纯度高，并经过滤除菌处理。本产品经SDS-PAGE电泳检测蛋白纯度和分子量参考图1。本产品经过滤除菌处理，可以直接用于培养细胞的刺激。

图1. Recombinant Human Soluble TNF-α (Trimeric form) (JP520)的SDS-PAGE电泳检测图。本产品经BeyoGel? Plus PAGE预制胶(Hepes, 4-20%, 10孔) (JP010523)电泳，蛋白Marker (M)为BeyoColor?彩色预染蛋白分子量标准(6.5-270kD) (JP010071/JP010072)，后续经BeyoBlue?考马斯亮蓝超快染色液(JP010017F)染色。实际效果会因样品种类、检测仪器等的不同而存在差异，图中数据仅供参考。
本产品可有效激活NF-κB的核转运信号通路，使JP6 (REL-associated protein, Rel-A)转移到细胞核内。稳定表达EGFP-JP6的HeLa细胞(C8001)经终浓度为10ng/ml的本产品刺激后EGFP-JP6进入细胞核，需要注意的是随着时间的延长EGFP-JP6会出核再次回到细胞质中，因此加入本产品后观察EGFP-JP6进入细胞核理想的时间为15-60分钟(图2)。

图2. Recombinant Human Soluble TNF-α (Trimeric form) (JP520)激活NF-κB信号通路诱导核转运的效果图。稳定表达EGFP-JP6的HeLa细胞(C8001)加入或不加入终浓度为10ng/ml的本产品，分别在0、30、60和120分钟用荧光显微镜进行拍照。可见在静息状态(Inactive state)下(Control)，EGFP-JP6均匀分布在细胞质中(第1行)；加入TNF-α刺激后，激活状态(Active state)下EGFP-JP6进入细胞核内(第2行，30分钟)，但是随着时间的延长EGFP-JP6会出核再次回到细胞质中(第2行，120分钟)。实际效果会因实验仪器、检测条件等的不同而存在差异，图中效果仅供参考。
本产品与SM-164 (XIAP抑制剂)联合使用可有效诱导细胞凋亡。100nM SM-164 (XIAP抑制剂) (SJP114)与不同浓度的本产品组成的细胞凋亡诱导剂，诱导BGC-823 (人胃癌细胞)(C6123)细胞凋亡的效果参考图3。

图3. Recombinant Human Soluble TNF-α (Trimeric form) (JP520)诱导细胞凋亡效果图。BGC-823 (人胃癌细胞) (C6123)经100nM SM-164 (XIAP抑制剂) (SJP114)与相应浓度的本产品组成的细胞凋亡诱导剂处理5-6小时，后续采用YO-PRO-1 (凋亡与坏死细胞绿色荧光探针) (C2022)对细胞进行染色。图中可见TNF-α三聚体(Trimer)的本产品比常规的TNF-α单体(monomer)有更强的细胞凋亡诱导效果。实际效果会因实验仪器、检测条件等的不同而存在差异，图中效果仅供参考。
本产品经尺寸排阻层析(Size-exclusion chromatography, SEC)验证为三聚体。人体中TNF-α为26kDa的单次跨膜蛋白，TNF-α被TACE/ADAM17 (TNF-α Converting Enzyme/A Disintegrin and Metalloprotease 17)在Ala76-Val77之间切割，成为游离于细胞膜外可溶形式的TNF-α (77-233aa)，无论是单次跨膜的TNF-α，还是游离于细胞膜外可溶形式的TNF-α，都以同源三聚体的构象行使其生物活性[4]。参考图4，本产品经16/60 Beyodex? 200pg验证为三聚体。

图4. Recombinant Human Soluble TNF-α (Trimeric form) (JP520)经使用16/60 Beyodex? 200pg进行凝胶过滤层析(也称尺寸排阻层析)分析确认为三聚体的参考图。牛血清白蛋白(Bovine Serum Albumin, BSA)分子量约为66kDa，是一种常见的蛋白分子量标准，在使用16/60 Beyodex? 200pg检测中A280nm实际出峰位置为78min (见绿色实线)。如果TNF-α为单体形式(TNF-α Monomer, 17.3kDa)，那么在使用16/60 Beyodex? 200pg检测中A280nm理论出峰位置应为95min (见紫色虚线)。本产品在使用16/60 Beyodex? 200pg检测中A280nm实际出峰位置为86min (见蓝色实线)，符合TNF-α三聚体形式(TNF-α Trimer, 51.9kDa)的出峰位置。实际检测结果可能会因样品和检测条件等的不同而存在差异，结果图仅供参考。

Background

Tumor necrosis factor alpha (TNF-α), also called cachectin, is the best-know member of the TNF-family, which can cause cell death. This protein is produced by neutrophils, activated lymphocytes, macrophages, NK cells, LAK cells, astrocytes endothelial cells, smooth muscle cells and some transformed cells. TNF-α occurs as a secreted, soluble form and as a membrane-anchored form, both of which are biologically active. The naturally-occurring form of TNF-α is glycosylated, but non-glycosylated recombinant TNF-α has comparable biological activity. The biologically active native form of TNF-α is reportedly a trimer. Human and murine TNF-α show approximately 79% homology at the amino acid level and cross-reactivity between the two species. Two types of receptors for TNF-α have been described and virtually all cell types studied show the presence of one or both of these receptor types.

Cytokine

Background

Macrophage Colony Stimulating Factor (M-CSF), also named CSF-1, is a hematopoietic growth factor that is involved in the proliferation, differentiation, and survival of monocytes, macrophages, and bone marrow progenitor cells. It is produced by osteoblasts (as a result of endocrine stimulation by parathyroid hormone) exerts paracrine effects on osteoclasts and can interact with CSF1R. M-CSF is a four α-helical bundle cytokine and its active form is found extracellularly as a disulfide-linked homodimer. Four transcript variants encoding three different isoforms have been reported for M-CSF gene. Although forms may vary, all of them contain the N-terminal 150a.a. portion that is necessary and sufficient for interaction with the receptor. The first 223a.a. of mature human M-CSF shares 88%, 86%, 81% and 74% sequence identity with corresponding regions of dog, cow, mouse and rat M-CSF, respectively. Human M-CSF is active in the mouse, but mouse M-CSF is reported to be species-specific.

Cytokine

Background

Pigment epithelium-derived factor (PEDF) is encoded by the SERPINF1 gene in humans and found in verebrates. It is a secreted phosphoglycoprotein that belongs to the clade F subfamily, serpin superfamily of proteinase inhibitors. The PEDF is a noninhibitory serpin with neurotrophic, anti-angiogenic, and anti-tumorigenic properties. It is synthesized as a 418a.a. about 50kDa precursor that contains a 19a.a. signal sequence and a 399a.a. mature region that shows a pyroglutamate at Gln20. Like other serpins, it contains three β-sheets, 810 α-helices, and a C-terminal RCL (reactive center loop). Unlike other serpins with Ser protease inhibiting activity. PEDF has functions of inducing extensive neuronal differentiation in retinoblastoma cells, inhibiting of angiogenesis. As it does not undergo the S (stressed) to R (relaxed) conformational transition characteristic of active serpins, it exhibits no serine protease inhibitory activity. PEDF is researched as a therapeutic candidate for treatment of such conditions as choroidal neovascularization, heart disease, and cancer.

Cytokine

Background

Thymic stromal lymphopoietin (TSLP) is a hemopoietic protein belonging to the cytokine family and is known to play an important role in the maturation of T cell populations through activation of antigen presenting cells. It is mainly expressed in a number of tissues including heart, liver and prostate. TSLP signals through a heterodimeric receptor complex composed of the thymic stromal lymphopoietin receptor and the IL-7R alpha chain. After binding STAT5 phosphorylation is induced resulting in the expression of downstream transcription factors. Like IL-7, TSLP induces phosphorylation of STAT3 and STAT5, but uses kinases other than the JAKs for activation. TSLP has the functions of enhancing the maturation of CD11c+ dendritic cells and inducing allergic inflammation by directly activating mast cells. It expression is linked to many disease states including asthma, inflammatory arthritis, atopic dermatitis, and eczema and other allergic states. But the factors inducing the activation of TSLP release are not clearly defined. Human TSLP shares approximately 43%a.a. sequence identity with mouse TSLP.

Cytokine

Background

Granulocyte-Macrophage Colony Stimulating Factor (GM-CSF) is secreted by a number of different cell types (including activated T cells, B cells, macrophages, mast cells, endothelial cells and fibroblasts) in response to cytokine or immune and inflammatory stimulation. It was initially characterized as a growth factor that can support the in vitro colony formation of granulocyte-macrophage progenitors and has functions of stimulates the growth and differentiation of hematopoietic precursor cells from various lineages. GM-CSF has also been reported to have a functional role on non-hematopoietic cells and can induce human endothelial cells to migrate and proliferate. Additionally, it can stimulate the proliferation of a number of tumor cell lines, including osteogenic sarcoma, carcinoma and adenocarcinoma cell lines. Human GM-CSF shares 54% sequences identity with mouse GM-CSF, but has no biological effects across species. GM-CSF is used as a medication to stimulate the production of white blood cells following chemotherapy and has also recently been evaluated in clinical trials for its potential as a vaccine adjuvant in HIV-infected patients.

Cytokine

Background

Granulocyte colony stimulating factor (G-CSF) is a pleiotropic cytokine. It is mainly produced by monocytes and macrophages upon activation by endotoxin, TNF-α and IFN-γ. Besides, many other cell types can secreted this protein after LPS, IL-1 or TNF-α activation, which are fibroblasts, endothelial cells, astrocytes and bone marrow stromal cells. Various carcinoma cell lines and myeloblastic leukemia cells can express G-CSF constitutively. G-CSF is cytokine that acts in hematopoiesis by controlling the production, differentiation, and function of 2 related white cell populations of the blood, the granulocytes and the monocytesmacrophages. In addition it may function in some adhesion or recognition events at the cell surface.
In humans, two distinct cDNA clones for G-CSF, encoding 207 and 204 amino acid (a.a.) precursor proteins, have been isolated. Both proteins have a 30a.a. signal peptide and have identical amino acid sequences except for a threea.a. insertion (deletion) at the 35tha.a. residue from the N-terminus of the mature protein. Human G-CSF is 73% identical at the amino acid level to murine G-CSF and the two proteins show species cross-reactivity.

Background

Stem Cell Factor (SCF) that binds to the c-Kit receptor is produced by fibroblasts and endothelial cells. The soluble and transmembrane forms of the protein are formed by alternative splicing of the same RNA transcript and the presence of both soluble and transmembrane SCF is required for normal hematopoietic function. SCF plays an important role in hematopoiesis, spermatogenesis, and melanogenesis. It also promotes mast cell adhesion, migration, proliferation, and survival. Human SCF shares 79%-87%a.a. sequence identity with canine, feline, mouse, and rat SCF. Furthermore, human SCF is weakly active on mouse cells.

保存条件:
-20℃或更低温度保存，至少一年有效。由于蛋白的每次冻融均会引起部分失活，所以首次配制成相应浓度的储存液后(请根据产品简介中Reconstitution一栏的信息配制储存液)，须分装后-20℃或更低温度冻存，以避免反复冻融。
注意事项:
由于有些塑料管壁对某些蛋白有较强的吸附作用，溶液中的蛋白很容易粘附在管壁上，并且粘附后的蛋白很难与管壁分离。而载体蛋白(Carrier protein，如0.1% BSA等)的主要作用是预先封闭塑料管壁上的蛋白结合位点，使细胞因子或重组蛋白不会粘附于管壁。所以一定要使用产品简介中Reconstitution一栏的信息配制储存液。
本产品仅限于专业人员的科学研究用，不得用于临床诊断或治疗，不得用于食品或药品，不得存放于普通住宅内。

Background

Interleukin-36 receptor antagonist (IL-36RA) is a secreted protein which belongs to the interleukin 1 cytokine family (IL-1 family) and it is predominantly expressed in keratinocytes but not in fibroblasts, endothelial cells or melanocytes. IL-36RA has been reported to antagonize the biological activity of IL-36α (IL-1F6), IL-36β (IL-1F8), and IL-36γ (IL-1F9). Furthermore, it could constitute part of an independent signaling system analogous to interleukin-1 alpha (IL-1A), beta (IL-1B) receptor agonist and interleukin-1 receptor type I (IL-1R1). In addition, The receptor for IL-36RA has not been positively identified. Indirect evidence suggests it is IL-1Rrp2. Recombinant human IL-36 RA contains 154 amino acid residues and it shares 91%a.a. sequence identity with murine IL-36RA.
