生物活性
描述 Propidium iodide (PI) is a red-fluorescent nuclear and chromosome counterstain which can bind to double stranded DNA by intercalating between base pairs. It is a cell impermeant dye, which can be excluded from viable cells. Thus it is widely used for the evaluation of apoptosis in different experimental models. Propidium iodide is excited at 488 nm and, with a relatively large Stokes shift, emits at a maximum wavelength of 617 nm.
