These Qa1 ELISA kits are immunodetection tools for measuring the levels of Qa1 in biological samples. Qa1 is an alias of the human HLA-E gene, which encodes the protein, major histocompatibility complex, class I, E. Notably, Qa1 is known to play a role in adaptive immune responses, among other functions. The HLA-E protein is described to be 358 amino acid residues in length and 40.1 kilodaltons in mass. Its subcellular localization is in the golgi, cell membrane, and is secreted. In terms of tissue specificity, it is reported to be expressed in secretory endometrial cells during pregnancy. This protein is known to be N-glycosylated and cleaved. Other names for this target antigen include HLA-6.2.
