产品描述

丝裂霉素C(Mitomycin C,MMC)是发现于头状链霉菌(S. caespitosus)的一种发酵产物,一种抗肿瘤抗生素。用作一种双链DNA(dsDNA)烷化剂,共价交联DNA,抑制DNA合成和细胞增殖。丝裂霉素C的活性发挥依赖于还原活化,或通过低pH、或通过DT-心肌黄酶、或通过NADH细胞色素c还原酶介导的方式发生。丝裂霉素C处理灭活小鼠胚胎成纤维细胞(MEF),使其在胚胎干细胞共培养体系中用作饲养细胞层。癌症研究中,丝裂霉素C选择性抑制DNA合成和突变,刺激遗传重组、染色体断裂和姐妹染色单体互换,以及诱导DNA修复。丝裂霉素C通过p53介导的通路诱导各种细胞发生凋亡。

注意事项

1) 关于化合物溶解性:产品特性内的“≥”表明溶于标示浓度,但饱和溶解度未知。不同批次化合物的溶解度会有差异。

2) 为了让化合物更好的溶解,可通过37℃加热或(和)超声波水浴中震动片刻来处理。若实验所需浓度过大甚至达产品溶解极限,请添加助溶剂助溶或自行调整浓度。

3) 本品仅用作科研用途,不可用于临床或诊疗用途。

4) 为了您的安全和健康,请穿实验服并戴一次性手套操作。

【温馨提示】:请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液;一旦配成溶液,请分装保存,避免反复冻融造成的产品失效。储备液置于-80°C避光保存,~6个月有效;-20°C避光保存,~1个月有效。建议本品用DMSO作为溶剂;如用H2O作为溶剂,建议现配现用,≤-20℃避光保存一周内使用。
【温馨提示】:关于丝裂霉素C的稳定性:酸性溶液中丝裂霉素C快速降解(pH<6.0),在pH 6-9的水溶性溶液中有可能维持活性。目前就该化合物在降解发生前在溶液中的保存时间仍存在争议。总的来说,保存在pH 6-9溶液中于0-5℃能存放一周;如果发生沉淀,建议重新配制溶液。因沉淀溶液已有证实对细胞有毒。由于该化合物遇光立即降解,需避光保存。

体内研究(动物模型):

动物模型(Animal Model):Four- to 6-wk-old NCr nude mice injected subcutaneously with 1 × 106 HCT116 (p53−/−) or 2 × 106 HT-29 cells

实验方法(Assay):Tumors were developed in the absence of treatment until they are ~0.2 cm in diameter. The mice were then subjected to the MMC and TRAIL treatment regimen. Animals were treated with MMC (1 mg/kg) by intraperitoneal injection for 24 h, followed by one intravenous dose of purified rhTRAIL (100 ug). As a negative control, a subset of the mice were injected (i.p. and i.v.) with saline (vehicle) at the same frequency of treatment. Animals were treated for 3 consecutive weeks.

体内研究(动物模型):

动物模型(Animal Model):20 female Wistar albino rats after tendon repair

实验方法(Assay):The animals were divided into two equal groups. In group 1, an injection of MMC (0.2 ml with 0.08 mg) was placed between the tendon and the skin of the right leg with a 27G dental needle, just after the final skin closure. In group 2, an identical volume of sterile normal saline was injected on the left side in a similar fashion. All the rats received four weekly injections of MMC (0.2 ml with 0.08 mg) and saline starting from the day of operation.
