Figure 2From: Regulation of Transgene Expression in Tumor Cells by Exploiting Endogenous Intracellular SignalsPhosphorylation of PPCs by PKCα in the presence or absence of DNA. The phosphorylation of the polymers or polymer/DNA complexes was determined by the radiolabel assay using [γ-32P]ATP. Data show mean ± SD (n = 3).CPM count per minute;C/A cation/anion charge ratioBack to article page
