The cells were incubated in 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*10^6 cells) for 45min at 4C. The secondary antibody used was FITC-conjugated Goat Anti-rabbit IgG (H+L) at 1:200 dilution for 35min at 4C. Control antibody (green line) was rabbit IgG (1ug/1*10^6 cells) used under the same conditions. Acquisition of >10,000 events was performed.Applications for KLRG1 Antibody (8E11) - BSA Free

Background: KLRG1
KLRG1's primary ligand is E-cadherin, which is expressed on non-neural epithelial tissues, but the KLRG1 receptor also recognizes both N- and R-cadherin expressed in nervous system tissues (1,3,5,6). E-cadherin binding of KLRG1 leads to ITIM triggering and, ultimately, either reduced T cell proliferation or decreased NK cell cytotoxicity (3,5,6). More precisely, upon differentiation of CD8+ T cells, cells switch from signaling through CD28 and instead signal through the inhibitory KLRG1 receptor molecule (3,4). Phosphorylation of KLRG1's ITIM causes recruitment of two phosphatases, SH2-containing inositol polyphosphate 5-phoshate (SHIP-1) and SH-2 containing protein-tyrosine phosphatase 2 (SHP-2) (3,5). The effectors SHIP-1 and SHP-2 degrade PIP3 to PIP2, preventing Akt phosphorylation and inhibiting proliferation (3,5,6). Conversely, when KLRG1 signaling is blocked in highly differentiated T cells, Akt signaling is restored and cell proliferation resumes (3). An increase in highly differentiated T cells is observed in many age-related infections such as meningitis, pneumonia, and influenza, which also correlates with elevated KLRG1 levels (3). This observation suggests that KLRG1 may be a potential immunotherapeutic target, especially for vaccinations which typically have decreased response in aged patients (3).
