DAPI染色溶液(DAPI Staining Solution)是适用于所有常见细胞和组织细胞核染色的染色液。 可以直接用于固定细胞或组织的细胞核染色。 1、DAPI是一种可以穿透细胞膜的蓝色荧光染料。和双链DNA结合后可以产生比DAPI自身强20多倍的荧光。和EB(ethidium bromide)相比，对双链DNA的染色灵敏度要高很多倍。 2、DAPI染色常用于细胞凋亡检测，染色后用荧光显微镜观察或流式细胞仪检测。DAPI也常3、用于普通的细胞核染色以及某些特定情况下的双链DNA染色。 |
| 产品介绍 | DAPI的最大激发波长为340nm，最大发射波长为488nm；DAPI和双链DNA结合后最大激发波长为364nm，最大发射波长为454nm。 |
| 生化机理 | DAPI is a cell-permeable DNA-binding dye which binds preferentially to DNA rich in adenine and thymine. It is used in flow cytometry for measuring nuclear DNA content or for sorting isolated chromosomes and is also useful for microscopic detection of nuclei and nuclear DNA in normal and apoptotic cells. DAPI can also be used to detect mycoplasma and in simple retrograde double-labelling procedures for studying axonal branching employing Evans Blue and Primulin. DAPI is a reversible inhibitor of S-adenosyl-L-methionine decarboxylase and KAO (diamine oxidase). |
