interaction of pyrene lipid labeled vsv with serum lipoproteins led to a spontaneous fast transfer of the small amount of pyrene fatty acids present in the envelope ( t1/2 less than or equal to 7 min ) , followed by a considerably slower transfer of pyrene phospholipids from the membrane of the virions ( t1/2 greater than or equal to 12 h ) .
