产品描述： 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.
