Protein Kinase C, phosphorylated (Ser-657/Tyr-658) (PKC)

May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Detects an 82kD protein corresponding to the molecular mass of phoshorylated PKCa on SDS-PAGE immunoblots of neonatal rat brain lysate. Similar results were seen in other PKCa-expressing cells, such as human SKN-SH, endothelial, and HeLa cells, as well as rabbit spleen fibroblasts and rat pituitary cells. In immunoprecipitation experiments with various PKC isoforms, this antibody detected PKCa and PKCb, but not other PKC isoforms in rat brain lysate.
