in contrast , analysis of flc membrane glycoproteins by cell surface labelling techniques ( i.e. , galactose-oxidase-borohydride techniques and polyacrylamide gel electrophoresis-fluorography ) or by metabolic labelling of glycoproteins with 3h-galactose , revealed consistent differences in the high mw region of the gels between parental in vitro passaged flc ( either 745 or 3cl-8 cells ) and clones derived from in vivo passaged cells .
