Immunogen NK cell clone E57 (CD2+, CD3-, CD7+, CD16+, CD56+)
Clone GL183
Isotype IgG1
Specificity GL183 monoclonal antibody immunoprecipitates the p58.2 molecule, a 58 kDa type I transmembrane protein (1-3). It can also react with a lighter (p50.2, 58 kDa) molecule, highly homologous to p58.2 in the extracellular area, but exhibiting a shorter cytoplasmic tail.(4,5) These p58.2 and 50.2 molecules are characterized by two immunoglobulin-like extracellular domains. They are expressed by human NK cell subsets and by human T lymphocytes subsets, the latest being, in most instances, CD8+CD4-TCR alpha beta+.(6,7) p58.2 and p50.2 are members of the newly described natural killer cell receptor (NK-R) family (for reviews, see 8,9). The GL183 antibody can restore in vitro the lysis by human NK clones of otherwise lysis-protected targets carrying the Cw3 or related alleles. GL183 antibody has been assigned to the CD158b cluster of differentiation of the VIth International Workshop on Human Leucocyte Differentiation Antigens (HLDA) in Kobe, 1996.
Characteristics MAb to Human CD158b (p58.2), Monoclonal antibody to Human CD158b (p58.2)
Purification Protein A Chromatography. Ascites
Alternative Name CD158b (p58.2) (KIR2DL2 Antibody Abstract)
Application Notes Flow cytometry: 2 µg / 5 x 105 cells (or 100 µL whole blood), per test. Studies on the recognition mechanisms and function of NK cells and CTLs. Analysis of the NK cell repertoire. Immunoprecipitation of p50.2 and p58.2 molecules. Each laboratory should determine an optimum working titer for use in its particular application. Other applications have not been tested but use in such assays should not necessarily be excluded.
