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 one 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 the polymorphisms specifying the peptide binding specificities, resulting in up to 4 different molecules. [provided by RefSeq]

FAQs for HLA DPA Antibody (NBP2-16851). (Showing 1 - 1 of 1 FAQ).

  1. We are planning to buy the HLA-DPA1 and HLA-DMB Abs from your company to do the IHC in our Tumor samples. We saw the image of the tissue, and my PI wants to know if you can send us the exact protocol you have used to do the IHC for NBP2-16851 and NBP1-85326?
    • These two antibodies should work with any general IHC-P protocol. Our general IHC-P protocol can be found here.
