Biotinylated Human HLA-G&B2M&Peptide (RIIPRHLQL) Complex Protein (Monomer, MALS verified)

Human leukocyte antigen-G (HLA-G) is a group of closely linked genes located on the short arm of human chromosome 6. Hla-g belongs to a non-classical major histocompatibility complex. MHC class I molecules are selectively highly expressed in extravvillous trophoblast cells invading the uterine decidual membrane.The gene structure of HLA-G is similar to that of HLA-A, HLA-B and HLA-C, but the termination code appears in advance so that the intracellular segment of protein product encoded by HLA-G is only 6 amino acids, which is significantly shorter than the 30 amino acids of classical HLA classI antigen. The Human HLA-G & B2M & RIIPRHLQL Complex Protein is a complex of HLA-G of the MHC Class I, B2M and RMFPNAPYL peptide.

Product Specifications

Background

Specifications

Biotinylated Human HLA-G&B2M&Peptide (RIIPRHLQL) Complex Protein is produced by co-expression of HLA and B2M loaded with RIIPRHLQL peptide. This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™) . The protein has a calculated MW of 36.3 kDa and 13.9 kDa. The protein migrates as 40-42 kDa and 15 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
