Flow cytometry techniques utilizing dual staining with annexin V and propidium iodide (PI) provide a robust method for quantitatively analyzing apoptosis induction. Annexin V binds phosphatidylserine exposed on the outer leaflet of the plasma membrane during early apoptosis. while PI permeates late apoptotic/necrotic cells. Simultaneous staining allows differentiation of viable. https://www.pomyslnaszycie.com/vegetable-glycerin-sale/
