Mouse monoclonal antibody to human CD244 molecule, natural killer cell receptor 2B4.
The CD244 antigen, also known as 2B4 / CD244, is a cell surface glycoprotein implicated in the regulation of natural killer and T lymphocyte function. The 2B4 / CD244 antigen identified on NK cells and T cells is capable of transmitting stimulatory signals and non-MHC-restricted killing. Reported as an activating receptor, human 2B4 / CD244 can effectively activate and enhance NK cell –mediated cytotoxicity, induce secretion of IFN-γ and matrix metalloproteinases (MMPs), as well as NK cell invasiveness. As a member of the CD2 subset of the Ig superfamily, CD244 is a high affinity ligand for CD48 and the interaction is essential for generation of NK effectors.
Human 2B4 / SLAMF4 / CD244. No cross-reactivity with human cell lysate ( 293 cell line ) in WB and ELISA. Human SLAMF1, Human cell lysate (293 cell line).
Recombinant Human 2B4 / SLAMF4 / CD244 Protein
Protein A affinity chromatography
Western blot: This antibody can be used at 1 - 2 μg/mL with the appropriate secondary reagents to detect Human 2B4 in WB. Using a DAB detection system, the detection limit for Human 2B4 is approximately 20 ng/lane under non-reducing conditions and 1 ng/lane under reducing conditions.
This antibody was produced from a hybridoma resulting from the fusion of a mouse myeloma with B cells obtained from a mouse immunized with purified, human cell-derived, recombinant Human 2B4 / SLAMF4 / CD244. The IgG fraction of the cell culture supernatant was purified by Protein A affinity chromatography.
