Product Details anti-2B4 Antibody

Characteristics: CD244 (also known as 2B4 Antigen) is a member of the CD2 subset of the immunoglobulin superfamily (CD2 IgSF).3,4,5 It is expressed on all natural killer (NK) cells, IL-2-activated NK cells (LAK), and a subset of T lymphocytes which mediate non-MHC-restricted cytotoxicity. The C9.1 antibody reacts with CD244.1, the 2B4 alloantigen which is expressed in most strains tested (A/J, AKR/N, BALB/c, CBA/N, C3H/He, DBA/1, DBA/2, NZB/N, SJL/J, 129/Svj), but not C57BL/6 or C58/J mice. The expression of the CD244.1 alloantigen on B lymphocytes that was originally described, has not been confirmed in later studies. The extracellular domain of CD244 is a ligand for another CD2 IgSF member, CD48. Two-color analysis of CD244.1 expression on splenic NK cells. BALB/c splenocytes were stained with either purified rat IgG2b, κ isotype control mAb A95-1 (Cat. No. 553986, left panel) or purified mAb C9.1 (right panel), followed by FITC-conjugated anti-rat IgG2b mAb RG7/11.1 (Cat. No. 553900) then PE-conjugated anti-mouse CD49b/Pan-NK Cells mAb DX5 (Cat. No. 553858). Flow cytometry was performed on a BD FACSCalibur™ flow cytometry system.
