CD158a/h/g Monoclonal Antibody (HP-MA4), APC, eBioscience™, Invitrogen™

Mouse Monoclonal Antibody

Description: The monoclonal antibody HP-MA4 recognizes several CD158 proteins, also known as KIR2D, specifically KIR2DL1 (CD158a), KIR2DS1 (CD158h), KIR2DS3, and KIR2DS5 (CD158g). It does not recognize KIR2DL2 (CD158b1), KIR2DS2 (CD158j), KIR2DL4 (CD158d) or KIR2DS4 (CD158i) and crossreactivity to KIR2DL3 (CD158b2) and KIR2DL5 (CD158f) are unknown. CD158 proteins are members of the killer cell immunoglobulin-like receptors (KIR) family of transmembrane glycoproteins that are expressed on NK cells and a subset of T cells. Each KIR has an isoform with either a short (S) or long (L) cytoplasmic domain which transduces either an activating or inhibitory signal, respectively. The crossreactivity of the HP-MA4 antibody to KIR2DS3 and KIR2DS5 was published in 2013. Applications Reported: This HP-MA4 antibody has been reported for use in flow cytometric analysis. Applications Tested: This HP-MA4 antibody has been pre-titrated and tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.125 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. Excitation: 633-647 nm; Emission: 660 nm; Laser: Red Laser. Filtration: 0.2 μm post-manufacturing filtered.
