we have used a protocol for internalization of ricin , a ligand binding to plasma membrane glycoproteins and glycolipids with terminal galactosyl residues , and infection with the vesicular stomatitis virus ts 045 mutant in bhk-21 cells to determine whether internalized plasma membrane molecules tagged by ricin reach distinct compartments of the biosynthetic-exocytic pathway .
