Plasma membrane asymmetry
WebJan 19, 2024 · Lipid asymmetry in the plasma membrane is a hallmark of living cells. 6,7,8,9,10,11,12 The loss of lipid asymmetry leads to exposure of PS at the cell surface, which occurs early during death ... WebThe strong plasma membrane asymmetry existing in living cells is lost on apoptosis, and it is commonly detected with the probes interacting strongly and specifically with phosphatidylserine (PS). This phospholipid becomes exposed to the cell surface, and the labeled annexin V is used for its detection. The requirement for early and Ca2 ...
