{"product_id":"v2592-100ug","title":"HLA-DRB1 Antibody Cocktail (MHC II)","description":"\u003cp\u003eThis mAb reacts with the beta-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 cytoplasmic 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":"100 ug \/ Mouse","offer_id":49474702770456,"sku":"V2592-100UG","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_5b048b9f-09d9-4d04-a250-ff3d95155ab7.jpg?v=1734441108","url":"https:\/\/danabiosci.com\/products\/v2592-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
