Figure 3From: Regulation of Transgene Expression in Tumor Cells by Exploiting Endogenous Intracellular SignalsThe level of endogenous PKCα and the activated form of PKCα, phospho-PKCα, in HepG2 cells.a HepG2 cell lysates andb recombinant PKCα (1 ng/lane) were immunoblotted with anti-PKCα serum or anti-phosphoPKCα (Ser657) serum. Bound antibodies were visualized using a chemiluminescence assayBack to article page
