Transverse movement of spin‐labeled phospholipids in the plasma membrane of a hepatocytic cell line (HepG2): Implications for biliary lipid secretion
P Muller, T Pomorski, S Porwoli, R Tauber, A Herrmann – 1 December 1996 – The redistribution of spin‐labeled phospholipid analogs across the plasma membrane of HepG2 cells, either in suspension or grown as monolayers, was investigated. After incorporation into the outer membrane leaflet spin‐labeled aminophospholipids phosphatidylserine (PS) and phosphatidylethanolamine (PE) moved rapidly to the inner monolayer, whereas the analog of phosphatidylcholine (PC) disappeared more slowly from the outer leaflet.
