Only our most reliable and effective kits qualify as Picokine, guaranteeing top-tier results for your assays.\u003cp\u003eCD28 (Cluster of Differentiation 28) is one of the proteins expressed on T cells that provide co- stimulatory signals required for T cell activation and survival. T cell stimulation through CD28 in addition to the T-cell receptor (TCR) can provide a potent signal for the production of various interleukins (IL-6 in particular). The CD28 gene is mapped to 2q33-q34. CD28 and CTLA-4, together with their ligands, B7-1 and B7-2, constitute one of the dominant costimulatory pathways that regulate T and B cell responses. CD28 and CTLA-4 are structurally homologous molecules that are members of the immunoglobulin (Ig) gene superfamily.\u003c\/p\u003e\u003ch3\u003eProduct information\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSupplier\u003c\/th\u003e\n\u003ctd\u003eBoster Bio\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eABMIUM evidence status\u003c\/th\u003e\n\u003ctd\u003eABMIUM Verified™ collaborator-tested data\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCatalogue reference\u003c\/th\u003e\n\u003ctd\u003eEK1429\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProduct category\u003c\/th\u003e\n\u003ctd\u003ePicoKine® ELISA Kits\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eReactive species\u003c\/th\u003e\n\u003ctd\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTested applications\u003c\/th\u003e\n\u003ctd\u003eELISA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGene name\u003c\/th\u003e\n\u003ctd\u003eCD28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eProtein name\u003c\/th\u003e\n\u003ctd\u003eT-cell-specific surface glycoprotein CD28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSample type\u003c\/th\u003e\n\u003ctd\u003ecell culture supernatants, cell lysates, serum and plasma (heparin, EDTA).\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAssay range\u003c\/th\u003e\n\u003ctd\u003e62.5 pg\/ml - 4,000 pg\/ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSensitivity\u003c\/th\u003e\n\u003ctd\u003e\u0026lt;12 pg\/ml\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecificity\u003c\/th\u003e\n\u003ctd\u003eNatural and recombinant human CD28\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eImmunogen\u003c\/th\u003e\n\u003ctd\u003eExpression system for standard: NS0; Immunogen sequence: N19-P152\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003eStore at 4℃ for 6 months, at -20℃ for 12 months.
