用途
用途
碘化丙啶(PI)是一种溴化乙啶的类似物,它在嵌入双链DNA后释放红色荧光。尽管PI不能通过活细胞膜,但却能穿过破损的细胞膜而对核染色。PI经常被用 来与Calcein-AM或者FDA等荧光化合物一起使用,能同时对活细胞和死细胞染色。
简介
碘化丙啶是一种可对DNA染色的细胞核染色试剂,常用于细胞凋亡检测,英文全称是Propidium Iodide。它是一种溴化乙啶的类似物,在嵌入双链DNA后释放红色荧光。
体外研究
Propidium Iodide is a cell-membrane impermeable dye with characteristic excitation maximum at 535 nm and emission maximum at 617 nm which intercalates with nucleic acids with a stoichiometry of one dye per 4-5 base pairs with little sequence preference. Propidium Iodide has evidenced of having no toxic effects on neurons, being today’s most common marker for membrane integrity and cell viability when applied prior to fixation (pre-fixation Propidium Iodide staining method). The pre-fixation staining has been widely used for quantitative assessments of neuronal cell decline in models of acute neurodegeneration, visualized as intensely labeled PI + -pycnotic nuclei of degenerating neurons . Propidium Iodide cannot cross the membrane of live cells, making it useful to measure the percentage of apoptotic cells by flow-cytometric analysis. The flow cytometric data shows an excellent correlation with the results obtained with both electrophoretic and colorimetric methods. This new rapid, simple and reproducible method proves useful for assessing apoptosis of specific cell populations in heterogeneous tissues such as bone marrow, thymus and lymph nodes.
生物活性
Propidium Iodide 是可用于细胞染色的红色荧光染料。
