应用

Bisbenzimide Hoechst 33342是双链高AT含量区域的特异染色剂,经证可替代几种已知的DNA嵌入剂。这种荧光染料已用于根据DNA含量分选活细胞选、流式细胞术DNA含量测定、活细胞染色质分布可视化。它已用于检测细胞BrdU掺入、细胞凋亡和细胞周期分配的初始阶段研究,。正在分裂或复制的染色体不会被这种染料染色。
适用于DNA,染色体和细胞核染色。可用于荧光显微镜或流式细胞术。
最大激发波=346nm
最大发射波长=460nm

生化/生理作用

膜透性,具有低细胞毒性荧光DNA染料,插入在DNA的A-T区域。

物理属性

双苯甲酰亚胺H 33342的荧光性质:
游离染料:最大激发波长= 340 nm,最大发射波长= 510 nm(5 mM HEPES, 10 mM NaCl, pH 7.0)DNA复合物:最大激发波长= 355 nm,最大发射波长= 465 nm (5 mM HEPES, 10 mM NaCl, pH 7.0)

制备说明

该产品可溶于水(50 mg/ml),形成澄清溶液。2%溶液的pH为1.9。现已观测发现此物质可从磷酸盐缓冲溶液中沉淀出来。
如果在2-8°C黑暗环境存放,水溶液可稳定保存1个月。
