CTLA-4 and CD28 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily. Both CTLA-4 and CD28 are composed of a single Ig V‑like extracellular domain, a transmembrane domain and an intracellular domain. CTLA-4 and CD28 are both expressed on the cell surface as disulfide-linked homodimers or as monomers. The genes encoding these two molecules are closely linked on human chromosome 2. CTLA-4 was originally identified as a gene that was specifically expressed by cytotoxic T lymphocytes. However, CTLA-4 transcripts have since been found in both Th1 and Th2, and CD4+ and CD8+ T cell clones. Whereas, CD28 expression is constitutive on the surfaces of 95% of CD4+ T cells and 50% of CD8+ T cells and is down regulated upon T cell activation, CTLA-4 expression is upregulated rapidly following T cell activation and peaks approximately 24 hours following activation. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with 20-100-fold higher affinity than CD28. The physiological role of CTLA-4 in T cell costimulation is currently being studied.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e:1 mg\/mL\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e:Recombinant Mouse CTLA4 protein expressed by Mammalian\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBuffer\u003c\/b\u003e:PBS with 0.02% sodium azide, 1% protective protein and 50% 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:IHC 1:500-1:1000\u003c\/p\u003e\u003cp\u003e\u003cb\u003eCalculated MW\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eObservedMW\u003c\/b\u003e:\u003c\/p\u003e","brand":"GeneBio Systems","offers":[{"title":"Default Title","offer_id":48644704829540,"sku":"AN006100L","price":154.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0558\/8588\/9636\/files\/no_image_default_image-jpeg_072b1e81-bddd-4c02-9681-3305dccd84d3.jpg?v=1782651364","url":"https:\/\/www.genebiosystems.com\/en-us\/products\/ctla4-polyclonal-antibody","provider":"GeneBio ","version":"1.0","type":"link"}
