CELLCYCLEANALYSIS
PROPIDIUM IODIDE: The most commonly used dye for DNA content/cell cycle analysis is PROPIDIUM IODIDE (PI). It can be used to stain whole cells or isolated nuclei. The PI intercalates into the major groove of double-stranded DNA and produces a highly fluorescent adduct that can be excited at 488 nm with a broad emission centred around 600 nm. Since PI can also bind to double-stranded RNA, it is necessary to treat the ......阅读全文
