Alterations in surface proteins of rat cells transformed by avian sarcoma virus B77.
Cell membrane proteins of avian sarcoma virus B77V--transformed cells LWF B55 and LWF B77 and uninfected rat embryo fibroblasts were analyzed by SDS acrylamide gel electrophoresis. Following alterations in cell surface proteins of LWF B55 and LWF B77 cells were found: one, a slight decrease of two high molecular weight proteins the larger of which corresponds presumably to "LETS" protein and a decrease of a protein with approximative molecular weight 50 000; two, increase in content of proteins with molecular weight of about 90--95 000 and 70--75 000 as well as a marked increase of a protein with molecular weight of 30--35 000.
