This antibody recognizes a common extracellular epitope on beta chain of human HLA DR and HLA DP. It reacts with alpha/beta dimer as well as with dissociated beta subunit. DR and DP are the isotypes of human MHC Class II molecules expressed on antigen-presenting cells (APC, dendritic cells, B lymphocytes, monocytes, and macrophages).
