{"product_id":"v2589ihc-7ml","title":"HLA-DRB1 Antibody (MHC II)","description":"\u003cp\u003eThis mAb reacts with a 28kDa chain of HLA-DRB1 antigen, a member of MHC class II molecules. It does not cross react with HLA-DP and HLA-DQ. 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. Loss of HLA-DR expression is related to tumor microenvironment and predicts adverse outcome in diffuse large B-cell lymphoma.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"7 ml \/ Mouse","offer_id":49474703229208,"sku":"V2589IHC-7ML","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_2fe5ae53-4026-49cc-b0a1-d16600aec99b.jpg?v=1734441137","url":"https:\/\/danabiosci.com\/products\/v2589ihc-7ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
