{"product_id":"v7845-20ug","title":"HLA-DRB1 Antibody","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":"20 ug \/ Mouse","offer_id":46704645570784,"sku":"V7845-20UG","price":249.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_d688c0c9-51d7-4378-add2-c641aca88961.jpg?v=1733338807","url":"https:\/\/rndmate.com\/products\/v7845-20ug","provider":"알앤디메이트","version":"1.0","type":"link"}
