the total amount of pkc activity in the quiescent versus proliferating cells was similar but the percentage of pkc activity in the membrane fraction correlated with the proliferative index of the cells : confluent , quiescent cultures exhibited a majority of pkc activity in the cytosolic fraction ( 67 % ) , whereas sparse , proliferating cultures contained principally membrane-bound pkc ( 70 % ) .
