Revvity, 64PLCG2Y7PEG, HTRF Human Phospho-PLC-γ2 (Tyr1217) Detection Kit, 500 Assay Points

Overview
This HTRF cell-based assay conveniently and accurately detects phosphorylated Phospholipase C gamma 2 (PLCgamma 2) at Tyr1217.
PLCgamma 2 is a phosphoinositide-specific phospholipase that generates second messengers and plays a crucial role in signal transduction, especially in haematopoietic cells such as B cells, mast cells, macrophages, natural killer cells and platelets. Upon stimulation of different receptors such as B-cell antigen receptor (BCR) and Fc receptors (FcRs), PLCgamma 2 interacts with several adapter proteins and becomes phosphorylated by intracellular tyrosine kinases. Phosphorylation includes several sites, one of which is Tyr1217.
PLCgamma 2 has been linked to various pathologies such as auto-immune and inflammatory diseases, drug-resistance in cancer and neurodegeneration.
How it works
Phospho-PLCg2 (Tyr1217) assay principle
The Phospho-PLCg2 (Tyr1217) assay measures PLCg2 when phosphorylated at Tyr1217. Unlike Western Blot, the assay is entirely plate-based and does not require gels, electrophoresis, or transfer. The assay uses 2 antibodies, one labeled with a donor fluorophore and the other with an acceptor. The first antibody was selected for its specific binding to the phosphorylated motif on the protein, the second for its ability to recognize the protein independently of its phosphorylation state. Protein phosphorylation enables an immune-complex formation involving both labeled antibodies, and which brings the donor fluorophore into close proximity to the acceptor, thereby generating a FRET signal. Its intensity is directly proportional to the concentration of phosphorylated protein present in the sample, and provides a means of assessing the protein's phosphorylation state under a no-wash assay format.

 

Phospho-PLCg2 (Tyr1217) two-plate assay protocol
The two-plate protocol involves culturing cells in a 96-well plate before lysis, then transferring lysates into a 384-well low volume detection plate before the addition of Phospho-PLCg2 (Tyr1217) HTRF detection reagents. This protocol enables the cells' viability and confluence to be monitored.

 

Phospho-PLCg2 (Tyr1217) one-plate assay protocol
Detection of Phosphorylated PLCg2 (Tyr1217) with HTRF reagents can be performed in a single plate used for culturing, stimulation, and lysis. No washing steps are required. This HTS designed protocol enables miniaturization while maintaining robust HTRF quality. Application-Cell Signaling
