Abstract: Protein kinase C (PKC), a calcium‐ and phospholipid‐dependent kinase, is highly enriched in rat brain, where it may function in signal transduction processes. We purified rat brain PKC to homogeneity by a three‐column procedure of diethylaminoethyl‐cellulose, phenyl‐Sepharose, and protamine‐agarose with a yield of 16% and a final specific activity of 9,600 pmol of [3H]phorbol‐12,13‐dibutyrate bound/mg of protein. The pure protein consisted of a doublet of 80 and 78 kilodaltons. Rabbit antibodies prepared against a β‐type PKC synthetic peptide sequence (RAKIGQGTKAPEEKTANTISK) showed high specificity and sensitivity for PKC and recognized only the 78‐kilodalton form of PKC. Micropunches (300 μm in diameter) of rat hippocampal subregions were solubilized in sodium dodecyl sulfate (SDS) sample buffer, electrophoresed on SDS–10% polyacrylamide gels, and transferred to nitrocellulose. PKC was visualized by 125I‐protein A autoradiography and quantified by densitometry. The highest concentrations of PKC were found in the CA1 pyramidal cell layer (0.43 ± 0.04 OD), with the lowest amounts in the CA3 and CA4 pyramidal cell layers (0.11 ± 0.02 and 0.085 ± 0.006 OD, respectively). These results demonstrate a simple way of preparing antibodies against domains of PKC. We also describe a procedure for quantifying the relative amounts of PKC in discrete brain regions.
