Purification notesPurified from rabbit antiserum by affinity chromatography using epitope specific phosphopeptide. The antibody against non phosphopeptide was removed by chromatography using non phosphopeptide corresponding to the phosphorylation site.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.
RelevanceProtein kinase C alpha and protein kinase C beta belong to the protein kinase superfamily, AGC Ser/Thr protein kinase family, PKC subfamily. Both contain 1 AGC kinase C terminal domain, 1 C2 domain, 2 phorbol ester/DAG type zinc fingers and 1 protein kinase domain. They are calcium activated, phospholipid dependent, serine and threonine specific enzymes. PKC alpha and may play a role in cell motility. PKC beta may be a novel component of the NF kappa B signaling axis responsible for the survival and activation of B cells after BCR cross linking. Both are activated by diacylglycerol which in turn phosphorylates a range of cellular proteins and both may also serve as the receptor for phorbol esters, a class of tumor promoters. PKC beta has two named isoforms produced by alternative splicing.
