Beschreibung

General description

The complement (C1q) and FcγR I binding sites of the Fcγ2a fragment allow the Fc portion of the fusion protein to effectively facilitate direct antibody directed cytotoxicity (ADCC) and complement directed cytotoxicity (CDC).

Biochem/physiol Actions

CD152 (CTLA4), a cell surface glycoprotein expressed at low levels on activated T cells, is a high affinity receptor for the costimulatory molecules CD80 (B7-1) and CD86 (B7-2). A related cell surface glycoprotein, CD28, binds to CD80 and CD86 with lower affinity. The soluble CD152/Fc chimeric fusion protein blocks the B7/CD28 signaling pathway by binding to CD80 and CD86.

Physical form

Solution, 0.2 μm filtered, in phosphate buffered saline, pH 7.4, with no preservative added.

Preparation Note

Purified from serum-free tissue culture supernatant

Other Notes

The extracellular domain (160 amino acids) of mouse CD152 is fused to mouse IgG2a Fc domain.
