Human REH cells (a non-T, non-B leukemia cell line) were used as the immunogen for the HLA-DRB1 antibody.
This MAb reacts with a 28kDa chain of HLA-DRB1 antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36kDa alpha (heavy) chain and a 28kDa beta (lig
