Anti-DRB1 antibodies enable researchers to detect and measure the DRB1 antigen in biological samples. This target is a reported synonym of the HLA-DRB1 gene, which encodes major histocompatibility complex, class II, DR beta 1. This protein is known to function in epidermis development and immune response pathways, among other biological roles. The human version of DRB1 has a canonical amino acid length of 266 residues and a protein mass of 30 kilodaltons. It is reported to be localized in the ER, lysosomes, and cell membrane of cells and notably expressed in the lymph node, lung, fallopian tube, bone marrow, and appendix. Indicated applications for DRB1 antibodies listed below include ELISA and Western Blot.
