Hoechst 33342 is a blue fluorescing dye that stains chromatin DNA. The red fluorescing dye propidium iodide is only permeable to dead cells and cannot enter the intact plasma membrane of living cells.

Nettet1. apr. 2016 · TMRM is a cell-permeable fluorescent dye that is sequestered to active mitochondria, and hence labels live cells. On apoptosis or necroptosis the TMRM signal is lost. NettetA feature of the early stages of programmed cell death is the disruption of mitochondrial function. This mitochondrial disruption includes changes in the membrane potential - a central feature of mitochondrial health, and alterations to the oxidation–reduction potential of the mitochondria. NettetHoechst 33342 and metachromatic dye acridine orange AO) can be taken up by both live and dead cells, which can be distinguished by their different morphology: live cells have flat nuclei with noncondensed chromatin and dead cells have small nuclei with condensed, sometimes fragmented chromatin. is littering illegal in canada
