Anti-Human CD244 Purified

Description: The eBioPP35 monoclonal antibody reacts with human CD244, also known as 2B4, p38, NK-cell activation-inducing ligand, signaling lymphocyte activation molecule family member 4, and natural killer cell receptor 2B4. Human CD244 is a 38 kD protein expressed on NK cells, a subset of CD8+ T cells, γδ T cells, monocytes, basophils, mast cells, and eosinophils. Binding of CD244 to its ligand, CD48, results in NK cell activation. Costaining experiments with eBioC1.7 suggest that both antibodies recognize different epitopes.
