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
Direct ELISA: This antibody can be used at 0.5 - 1 μg/mL with the appropriate secondary reagents to detect Human 2B4. The detection limit for Human 2B4 is approximately 0.039 ng/well.
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.
0.2 μm filtered solution in PBS with 5% trehalose
This antibody can be stored at 2-8 °C for one month without detectable loss of activity. Antibody products are stable for twelve months from date of receipt when stored at -20 °C to -70 °C. Preservative-Free.Sodium azide is recommended to avoid contamination (final concentration 0.05%-0.1%). It is toxic to cells and should be disposed of properly. Avoid repeated freeze-thaw cycles.
