LAT (pY226) Monoclonal / PE-Vio770 / REA146

Product Details

Description	Clone REA146 recognizes LAT phosphorylated at tyrosine 226. Linker of T cell activation (LAT), a transmembrane adaptor molecule, is constitutively localized in the lipid rafts and is involved in transducing the signal initiated by triggered T cell receptor (TCR). Upon TCR engagement, SRC and SYK family of protein tyrosine kinases (PTKs) are activated and LAT is phosphorylated at multiple conserved tyrosine residues in its cytosolic domain by Syk-family PTK Zap-70. Phosphorylated LAT can associate with several downstream SH2 domain containing proteins such as GRB2, PLCy1, ITK, GADS, and p85 subunit of PI3K to propagate the TCR activation signal and to activate several downstream pathways. pY226 motif can be bound directly by GRB2, GADS, and PLC-y1. Expression of LAT is found in thymocytes, T cells, mast cells, natural killer (NK cells), and platelets. Thymocytes lacking LAT are completely blocked at the pro-T3 stage in thymopoiesis. \| Additional information: Clone REA146 displays negligible binding to Fc receptors. \|

About PE-Vio770
PE-Vio® 770 from Miltenyi Biotec is a red-emitting tandem fluorophore that combines pycoerythrin (PE) and Vio®770. The donor molecule, PE can be excited by the 488-nm blue, 532-nm green, or 561-nm yellow-green laser and and transfers energy to the acceptor molecule, Vio®770, which emitts light that can be captured with a 780/60 nm bandpass filter. PE-Vio®770 has an excitation peak at 565 nm and an emission peak at 775 nm and is a common alternative to PE-Cy7 and PE-H7.
