This antibody recognises CD74, a type II transmembrane protein, which is also known as the MHC class II associated invariant chain. The Bu45 antibody recognises 33, 35 and 41 kDa isoforms of CD74. The Bu45 antibody binds to an epitope within the extracytoplasmic domain of the CD74 Molecule, which is distal from the C-terminus. *Membrane permeabilisation may enhance CD74 staining on monocytes but is not required when staining lymphocytes.

The CD74 Molecule plays a critical role in the presentation of peptides, by the MHC class II antigens, to CD4 positive lymphocytes. CD74 is expressed on MHC class II positive cells including B cells, a subset of activated T cells, monocytes, dendritic cells and by various types of carcinoma. Expression of CD74 is primarily intracellular with moderate expression at the cell surface of B cells and monocytes.Synonyms: DHLAG, HLA class II histocompatibility antigen gamma chain, HLA-DR antigens-associated invariant chain, Ia antigen-associated invariant chain, p33
