As costimulatory ligands, B7-1 which exists predominantly as dimer and the related protein B7-2, interact with the costimulatory receptors CD28 and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expressed on T cells, and thus constitute one of the dominant pathways that regulate T cell activation and tolerance, cytokine production, and the generation of CTL. The B7\/CD28\/CTLA4 pathway has the ability to both positively and negatively regulate immune responses. CD80 is thus regarded as promising therapeutic targets for autoimmune diseases and various carcinomas.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eConcentration\u003c\/b\u003e:\u003c\/p\u003e\u003cp\u003e\u003cb\u003eActivity\u003c\/b\u003e:Not validated for activity\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSequence\u003c\/b\u003e:Val35-Asn242\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e: \u0026gt; 90% as determined by reducing SDS-PAGE.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFormulation\u003c\/b\u003e:Lyophilized from a 0.2 μm filtered solution in PBS with 5% Trehalose and 5% Mannitol.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e:It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg\/mL.
