Specificity / Sensitivity

Each antibody in the PLCγ Antibody Sampler Kit detects endogenous levels of its target protein. The antibodies do not cross react with other PLCs.

Western Blotting

Western Blotting

Western blot analysis of extracts from 3T3 cells, untreated or treated with PDGF alone or PDGF and CIP/λ phosphatases, using Phospho-PLCγ1 (Tyr783) Antibody #2821 (upper) or PLCγ1 Antibody #2822 (lower).

Western Blotting

Western Blotting

Western blot analysis of extracts from Ramos cells, untreated or treated with anti-human IgM, using Phospho-PLCγ2 (Tyr1217) Antibody #3871 (upper), Phospho-PLCγ2 (Tyr 759) Antibody #3874 (middle), or PLCγ2 Antibody #3872 (lower).

Western Blotting

Western Blotting

Western blot analysis of extracts from NIH/3T3 (lanes 1, 3, 5) and Ramos (lanes 2, 4, 6) cells, using PLCγ1 Antibody #2822 (lanes 1 and 2), PLCγ2 Antibody (lanes 5 and 6) or both antibodies (lanes 3 and 4). Results show that PLCγ2 Antibody is specific to the 150 kDa PLCγ2 band detected in Ramos cells, while PLCγ1 Antibody #2822 is specifc to the 160 kDa PLCγ1 band detected in both Ramos and NIH/3T3 cells.


Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using PLCγ1 (D9H10) XP® Rabbit mAb #5690.

Description

PLCγ Antibody Sampler Kit provides an economical means of analyzing phospho and total PLCγ levels. PLCγ Antibody Sampler Kit contains enough primary and secondary antibodies to perform four western blot experiments with each antibody.

Source / Purification

PLCγ1 monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Leu1220 of human PLCγ1 protein.Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding human PLCγ1 and PLCγ2. Antibodies are purified by protein A and peptide affinity chromatography.

Background

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) (1). At least four families of PLCs have been identified: PLCβ, PLCγ, PLCδ, and PLCε. Phosphorylation is one of the key mechanisms that regulate the activity of PLC. PLCγ is activated by both receptor and non-receptor tyrosine kinases (2). PLCγ forms a complex with EGF and PDGF receptors, which leads to the phosphorylation of PLCγ at Tyr771, 783, and 1245 (3). Phosphorylation by Syk at Tyr783 activates the enzymatic activity of PLCγ1 (4). PLCγ2 is engaged in antigen-dependent signaling in B cells and collagen-dependent signaling in platelets. Phosphorylation by Btk or Lck at Tyr753, 759, 1197, and 1217 is correlated with PLCγ2 activity (5,6).
