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
