KLRG1 Monoclonal Antibody (2F1), Super Bright™ 780, eBioscience™, Invitrogen™

Description

Description: The TER-119 monoclonal antibody reacts with mouse erythroid cells from early proerythroblast to mature erythrocyte stages. The TER-119 antigen is present in yolk sac, fetal and newborn liver, but is not expressed by cells carrying BFU-E and CFU-E activities. Several erythroleukemia cell lines tested so far are negative for expression of TER-119 antigen even after dimethylsulfoxide stimulation. Biochemical and molecular analysis of the TER-119 antigen indicate that this molecule is associated with the surface glycophorin A, but is not a typical glycophorin. Applications Reported: This TER-119 antibody has been reported for use in flow cytometric analysis. Applications Tested: This TER-119 antibody has been tested by flow cytometric analysis of mouse bone marrow cells. This may be used at less than or equal to 1.0 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Super Bright 780 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 780 nm. We recommend using a 780/60 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome.

KLRG1 (Killer cell lectin-like receptor G1, MAFA, 2F1-Ag) is a homodimeric member of the lectin-like type 2 transmembrane receptor family whose members contain characteristic immunoreceptor tyrosine-based inhibitory motifs (ITIMs) in their cytoplasmic domains. These ITIMs interact with the SH2 domains of protein phosphatases such as SHP-1. KLRG1 is an inhibitory receptor that is expressed on natural killer (NK) cells and certain T cells. NK cells are involved in the lysis of tumor cells and virus-infected cells, and mediate humoral and cell-mediated immune responses.
