ELISA Data Immobilized APC-equivalent Human HLA-G&B2M&Peptide (RIIPRHLQL) Tetramer, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Anti-HLA-G&B2M&Peptide (RIIPRHLQL) Antibody, hFc Tag with the EC50 of 2.5ng/ml determined by ELISA (QC Test). Blocking Data Serial dilutions of Anti-LILRB2 Antibody were added into APC-equivalent Human HLA-G&B2M&Peptide (RIIPRHLQL) Tetramer, His Tag: Human LILRB2, mFc Tag binding reactioins. The half maximal inhibitiory concentration (IC50) is 62.7 ng/ml.

Background :
HLA-G is a molecule that was first known to confer protection to the fetus from destruction by the immune system of its mother, thus critically contributing to fetal-maternal tolerance. The first functional finding constituted the basis for HLA-G research and can be summarized as such: HLA-G, membrane-bound or soluble, strongly binds its inhibitory receptors on immune cells (NK, T, B, monocytes/dendritic cells), inhibits the functions of these effectors, and so induces immune inhibition.

Synonyms :
HLA G antigen; sHLA-G; b2 microglobulin; HLA G; HLAG; HLA-G; MHC Class I Antigen G; MHC class Ib antigen; MHC-G; sHLA-G
