This class II molecule is a heterodimer consisting of an alpha (DRA) and a beta (DRB) chain, 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 and its gene contains 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. Typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. DRB1 is expressed at a level five times higher than its paralogues DRB3, DRB4 and DRB5. The presence of DRB4 is linked with allelic variants of DRB1, otherwise it is omitted. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e: 1.02 mg\/mL\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e: Fusion protein of human HLA-DRB4\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBuffer\u003c\/b\u003e: PBS with 0.05% NaN3 and 40% Glycerol,pH7.4\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification method\u003c\/b\u003e: Antigen affinity purification\u003c\/p\u003e\u003cp\u003e\u003cb\u003eDilution\u003c\/b\u003e: WB 1:500-1:2000;IHC 1:20-1:100\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e: 30 kDa\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e: Refer to figures\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48053187280996,"sku":"E-AB-18812","price":489.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_a8e15399-3de2-4431-8b40-ab5410fe7447.jpg?v=1773339273","url":"https:\/\/www.genebiosystems.com\/en-fr\/products\/hla-drb4-polyclonal-antibody","provider":"GeneBio ","version":"1.0","type":"link"}
