用途 |
DAPI荧光染料,可穿透细胞膜与细胞核双链DNA结合发挥标记作用,产生比自身强20多倍荧光,对双链DNA染色灵敏度高EB很多倍.显微镜下看显蓝色荧光细胞,荧光效率几乎为100%,且对活细胞无毒副作用.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.也用于普通细胞核染色及某些特定情况下的双链DNA染色.

用途 |
一种与富含A-T序列的DNA结合的荧光染料。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).
