The class II molecule is a heterodimer consisting of an alpha (DRA) and a beta chain (DRB), 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 beta chain is approximately 26-28 kDa. It is encoded by 6 exons. Exon one encodes the leader peptide; exons 2 and 3 encode the two extracellular domains; exon 4 encodes the transmembrane domain; and exon 5 encodes the cytoplasmic tail. Within the DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Hundreds of DRB1 alleles have been described and typing for these polymorphisms is routinely done for bone marrow and kidney t\u003c\/p\u003e\n\n\u003cp\u003eCondition: Liquid in PBS containing 50% glycerol, 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: WB 1:500-2000 ELISA 1:5000-20000\u003c\/p\u003e\n\n\u003cp\u003eApplications: WB; ELISA\u003c\/p\u003e\n\n\u003cp\u003eSpecies Cross-Reactivity: Human; Rat; Mouse\u003c\/p\u003e\n\n\u003cp\u003eGeneID (Human): 3123\u003c\/p\u003e\n\n\u003cp\u003eProtein MW (KDa): 29\u003c\/p\u003e\n\n\u003cp\u003eSWISS: P01911\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":45120412090547,"sku":"RA30911-50","price":336.0,"currency_code":"CAD","in_stock":true},{"title":"100μL","offer_id":45120412123315,"sku":"RA30911-100","price":448.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0305\/9482\/6376\/files\/logo_936cd730-5e26-42c6-a085-99a7b737fe33.png?v=1773364987","url":"https:\/\/afsbio.com\/products\/2b1f-polyclonal-antibody-ra30911","provider":"AFSBio Inc.","version":"1.0","type":"link"}
