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. It is encoded by 5 exons; exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, and exon 4 encodes the transmembrane domain and the cytoplasmic tail. 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. Typing for these polymorphisms is routinely done for bone marro\u003c\/p\u003e\n\n\u003cp\u003eCondition: Liquid in PBS containing 50% glycerol, 0.5% BSA and 0.02% sodium azide.\u003c\/p\u003e\n\n\u003cp\u003eStorage Instructions: -20°C\/1 year\u003c\/p\u003e\n\n\u003cp\u003eRecommended dilutions: IHC-p 1:50-200, ELISA 1:10000-20000\u003c\/p\u003e\n\n\u003cp\u003eAlternative Names: HLA class II histocompatibility antigen, DQ alpha 1 chain (DC-1 alpha chain;DC-alpha;HLA-DCA;MHC class II DQA1)\u003c\/p\u003e \n\n\u003cp\u003eApplications: IHC-p; IF (paraffin section) ; ELISA\u003c\/p\u003e\n\n\u003cp\u003eSpecies Cross-Reactivity: Human\u003c\/p\u003e\n\n\u003cp\u003eGeneID (Human): 100509457\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P01909\u003c\/p\u003e\n\n\u003cp\u003eSource: Rabbit\u003c\/p\u003e\n\n\u003cp\u003eResearch Use Only\u003c\/p\u003e","brand":"Reed Bio","offers":[{"title":"50μL","offer_id":45120316670131,"sku":"RA25968-50","price":336.0,"currency_code":"CAD","in_stock":true},{"title":"100μL","offer_id":45120316702899,"sku":"RA25968-100","price":448.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/logo_adae96c1-f393-4df2-976f-ea30411679dc.png?v=1773356991","url":"https:\/\/afsbio.com\/products\/hla-dqa1-polyclonal-antibody-ra25968","provider":"AFSBio Inc.","version":"1.0","type":"link"}
