quantitative two-dimensional gel electrophoretic analysis ( isoelectric focusing ) of [ 35s ] methionine-labeled polypeptides from basal cells and simian virus 40-transformed keratinocytes showed that the basal cells synthesize very low amounts ( less than 0.02 % of the total protein ) of the nuclear , transformation-sensitive protein cyclin as compared to the transformed cells , which synthesize this protein constitutively ( 0.15 % of the total protein ) .
