产品信息

产品描述

9-氨基-6-氯-2-甲氧基吖啶（9-Amino-6-chloro-2-methoxyacridine, ACMA）是一种细胞通透性的荧光探针，一种DNA嵌入剂，选择性结合poly (dA-dT)序列，随着插入鸟苷荧光寿命逐渐减少。ACMA能用于DNA标记，激发/发射波长为411/475n，可采用大多数紫外光源激发，因而兼容更短和更长波长的染料。ACMA荧光依赖pH，并在形成pH梯度时淬灭，这一特征被用于基于动物和植物的研究中。ACMA也抑制胆碱酯酶活性，Ki为49nM。

Assay：Liposomal fluorimetric assay 

Method：The pH sensitive dye 9-amino-chloro-2-methoxyacridine (ACMA) was added to a final concentration of 2 μM from a freshly prepared 200 μM stock in 100% (v/v) ethanol. Fluorescence emission at 483 nm (excitation at 419 nm) was monitored over time with pathlengths of 2 and 10 mm for excitation and emission, respectively.

Assay：9-Amino-6-chloro-2-methoxyacridine (ACMA) fluorescence assay to detect Na+/H+ antiport activity

Method：Na+/H+ antiporter activity was measured in a thermostated cuvette containing a continuously stirred suspension of 2 ml of 10 mM Tris–HEPES at various pH (6.0–8.0), 140 mM choline chloride, 5 mM MgCl2, 2 μM ACMA and membranes (200 μg of protein). The changes in pH inside the membranes were monitored by following the (de)quenching of ACMA fluorescence (excitation 410 nm; emission 480 nm).
