Description: The eBioDM244 monoclonal antibody reacts with human CD244 (2B4, p38). In human, CD244 is a 38 kDa protein expressed on NK cells, a subset of CD8+ T cells, gammadelta T cells, monocytes, basophils and eosinophils. Binding of the CD244 ligand, CD48, results in NK cell activation, unlike mouse CD244, which is an inhibitory receptor.
Applications Reported: This eBioDM244 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This eBioDM244 antibody has been pre-titrated and tested by flow cytonetric 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.
CD244 (2B4, SLAMF4) is a cell surface receptor expressed on natural killer (NK) cells (and some T cells) that mediate non-major histocompatibility complex (MHC) restricted killing. The interaction between NK-cell and target cells via CD244 is thought to modulate NK-cell cytolytic activity. CD244 interacts with SLAMF2, causing the activation of both SLAMF4- and SLAMF2-expressing cells. Patients with systemic lupus erythmatosus have lower than normal levels of SLAMF4 expressed on their NK cells and monocytes, suggesting that SLAMF4 may play a role in the pathology of this autoimmune disease. Diseases associated with CD244 dysfunction include rheumatoid arthritis and lymphoproliferative syndrome. Alternatively spliced transcript variants encoding different isoforms of CD244 have been found for this gene.
