{"product_id":"new-product-228641","title":"HLA-DQA1 polyclonal antibody","description":"\u003cp\u003eHLA-DQA1 belongs to the HLA class II alpha chain paralogues. The class II molecule is a heterodimer consisting of an alpha (DQA) and a beta chain (DQB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B Lymphocytes, dendritic cells, macrophages). The alpha chain is approximately 33-35 kDa. Within the DQ molecule both the alpha chain and the beta chain contain the polymorphisms specifying the peptide binding specificities, resulting in up to four different molecules.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse","offer_id":47662384185624,"sku":"BS6917","price":408.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_124954fb-e8b2-4c88-b0ba-a4479fb3aa7e.jpg?v=1707485698","url":"https:\/\/danabiosci.com\/products\/new-product-228641","provider":"Dana Bioscience","version":"1.0","type":"link"}
