It is a member of the immunoglobulin superfamily, which is expressed on the surface of Helper T cells and transmits an inhibitory signal to T cells. CTLA4 is similar to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Blockade of CTLA4 expression in vitro augmented HIV-specific CD4-positive T-cell function.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eImmunogen\u003c\/b\u003e: E.coli-derived human CTLA4 recombinant protein (Position: N110-N223).\u003c\/p\u003e\u003cp\u003e\u003cb\u003eClonality\u003c\/b\u003e: Polyclonal\u003c\/p\u003e\u003cp\u003e\u003cb\u003eContents\u003c\/b\u003e: Each vial contains 4mg Trehalose, 0.9mg NaCl, 0.2mg Na2HPO4.\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurification\u003c\/b\u003e: Immunogen affinity purified.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReconstitution\u003c\/b\u003e: Add 0.2ml of distilled water will yield a concentration of 500ug\/ml.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eReference\u003c\/b\u003e: 1.
