Western blot analysis of PLCγ1 immunoprecipitates from human jurkat cells untreated (lanes 1 & 3) or treated with pervanadate (1 mM) for 30 min (lanes 2,4,5,6). Immunoprecipitation was performed with anti-PLCγ1 (PM1561). The blots were probed with anti-PLCγ1 (lanes 1 & 2) and anti-PLCγ1 (Tyr-775) (lanes 3-6). The latter antibody was used in the presence of phospho- PLCγ1 (Tyr-775) peptide (lane 5), or unrelated phosphotyrosine peptide (lane 6).

Bulk Order Anti-PLCγ1 (Tyr-775), Phosphospecific Antibody
Phosphoinositide-specific phospholipase C (PLC) plays a significant role in transmembrane signaling. In response to extracellular stimuli such as hormones, growth factors, and neurotransmitters, PLC hydrolyzes phosphatidylinositol 4,5-bisphosphate (PIP2) to generate two secondary messengers: inositol 1,4,5-triphosphate (IP3) and diacylglycerol (DAG). At least four families of PLCs have been identified: PLCβ, PLCγ, PLCδ, and PLCε. Phosphorylation is one of the key mechanisms that regulates the activity of PLC. PLCδ is activated by both receptor and nonreceptor tyrosine kinases. PLCγ1 forms a complex with EGF and PDGF receptors, which leads to phosphorylation at tyrosine 771, 783, and 1245. In addition, antigen receptor-induced activation of PLCγ1 leads to phosphorylation at both Tyr-775 and Tyr-783. These two sites are equally important for activation of enzymatic activity.
Antigen Affinity Purified
ICC, IP, WB
PLCγ1 (Tyr-775) synthetic peptide (coupled to carrier protein) corresponding to amino acids around tyrosine 775 in human PLCγ1. This sequence has high homology to the conserved site in rat and mouse PLCγ1, and has low homology to PLCγ2.

Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C.
PBS + 1 mg/ml BSA, 0.05% NaN3 and 50% glycerol
This antibody was cross-adsorbed to a non-specific phospho-tyrosine peptide then affinity-purified using phospho-PLCγ1 (Tyr-775) peptide. The antibody detects a 150 kDa* protein in human Jurkat and A431 cells treated with pervanadate, but is not observed in untreated cells.
