Anti-HLA-DPB antibodies are protein reagents that detect specific antigens. The HLA-DPB antigen is another term for the human protein major histocompatibility complex, class II, DP beta 1, encoded by the HLA-DPB1 gene. The protein is known to bind peptides derived from antigens that access the endocytic route of antigen presenting cells (APC) and presents them on the cell surface for recognition by the CD4 T-cells. Canonically, it has an amino acid length of 258 residues and a mass of 29.2 kilodaltons. Its subcellular localization is in the ER, Golgi, lysosomes, and cell membrane and it is widely expressed in many tissue types. The HLA-DPB protein is a member of the MHC class II protein family. Other alias names for HLA-DPB include DPB1, HLA-DP, and HLA-DP1B. Indicated applications for HLA-DPB antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
