Recombinant Anti-HLA DR Antibody [HLA-DRA/6844R] - BSA and Azide free (A316478)

Anti-HLA DR Antibody [HLA-DRA/6844R] - BSA and Azide free

Recombinant rabbit monoclonal [HLA-DRA/6844R] antibody to HLA DR.

This MAb reacts with the beta-chain of HLA-DR antigen, a member of MHC class II molecules. s respective epitopes. HLA-DR is a heterodimeric cell surface glycoprotein comprised of a 36kDa alpha (heavy) chain and a 28kDa beta (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. It is an excellent histiocytic marker in paraffin sections producing intense staining. True histiocytic neoplasms are similarly positive. HLA-DR antigens also occur on a variety of epithelial cells and their corresponding neoplastic counterparts.
