The antibody detects endogenous levels of BLK only when phosphorylated at tyrosine 501.
Purification
Antibodies were purified by affinity-chromatography using epitope-specific peptide.
Immunogen
BLK (phospho Tyr501) antibody was raised against a peptide sequence around phosphorylation site of tyrosine 501 (R-Q-Y (p)-E-L) derived from Human BLK.
Non-receptor tyrosine kinase involved in B-lymphocyte development, differentiation and signaling. B-cell receptor (BCR) signaling requires a tight regulation of several protein tyrosine kinases and phosphatases, and associated coreceptors. Binding of antigen to the B-cell antigen receptor (BCR) triggers signaling that ultimately leads to B-cell activation. Signaling through BLK plays an important role in transmitting signals through surface immunoglobulins and supports the pro-B to pre-B transition, as well as the signaling for growth arrest and apoptosis downstream of B-cell receptor.
