The L243 monoclonal antibody binds to the human HLA-DR antigen, a 36-kDa alpha heavy chain and a 27- kDa beta light chain heterodimeric cell surface glycoprotein in transmembrane major histocompatibility complex 2 (MHC II) family^{1, 2}. HLA-DR, also known as human leukocyte antigen DR isotype, is present on the surface of antigen-presenting cells, including B cells, dendritic cells, macrophages, monocytes and activate T cells. MHC class II regulates the immune system by playing a critical role in binding and presenting antigen-derived peptides to peptide-MHC II-specific CD4 T cells³.

The antibody was purified by affinity chromatography and conjugated with a fluorophore under optimal conditions.
