Product Specific Information

This antibody recognizes an extracellular epitope at the C-terminus of the alpha-2 helix and a turn on one of the underlying beta strands within the human HLA-A2 histocompatibility antigen.

Target Information

HLA-A belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane. Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. They are expressed in nearly all cells.

The heavy chain (~45 kDa) gene contains 8 exons:

1. Exon 1 – leader peptide
2. Exons 2 & 3 – α1 and α2 domains (peptide-binding)
3. Exon 4 – α3 domain
4. Exon 5 – transmembrane region
5. Exons 6 & 7 – cytoplasmic tail

Polymorphisms within exon 2 and exon 3 determine peptide-binding specificity. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. Hundreds of HLA-A alleles have been described.

HLA and MHC antibodies play a significant role in Immunopeptidomics, aiding neoantigen identification and characterization via high-performance liquid chromatography coupled to tandem mass spectrometry.
