Product Specific Information

This antibody detects endogenous levels of total HLA-DPA1.

Target Information

HLA-DPA1 belongs to the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha (DPA) and a beta (DPB) chain, both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen-presenting cells (APC: B lymphocytes, dendritic cells, macrophages).

The alpha chain is approximately 33–35 kDa and its gene contains 5 exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and the cytoplasmic tail. Within the DP molecule, both the alpha chain and the beta chain contain polymorphisms specifying peptide-binding specificities, resulting in up to four different molecules.

HLA and MHC antibodies play a significant role in immunopeptidomics, facilitating the identification and characterization of neoantigens through high-performance liquid chromatography coupled to tandem mass spectrometry.
