{"product_id":"v2585ihc-7ml","title":"HLA-DR Antibody (MHC II)","description":"\u003cp\u003eThis mAb reacts with the HLA-DR 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 cytoplasmic staining. True histiocytic neoplasms are similarly positive. HLA-DR antigens also occur on a variety of epithelial cells and their corresponding neoplastic counterparts.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"7 ml \/ Mouse","offer_id":49474704015640,"sku":"V2585IHC-7ML","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_a6517c2b-2b7a-4df4-95e9-41e3c0a1a8a9.jpg?v=1734441195","url":"https:\/\/danabiosci.com\/products\/v2585ihc-7ml","provider":"Dana Bioscience","version":"1.0","type":"link"}
