产品描述： Description

HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36 kD α (heavy) chain and a 27 kD

β (light) chain. It is expressed on B cells, activated T cells, monocytes/macrophages, dendritic cells, and

other non-professional APCs. In conjunction with the CD3/TCR complex and CD4 molecules, HLA-DR is

critical for efficient peptide presentation to CD4+ T cells.
