Background: CD86; also known as B-lymphocyte activation antigen B7-2 (referred to as B70); is a member of the cell surface immunoglobulin superfamily. B7-2 exists predominantly as a monomer on cell surfaces and interacts with two co-stimulatory receptors CD28 and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) expressed on T cells; and thus induces the signal pathways which regulate T cell activation and tolerance; cytokine production; and the generation of CTL. It is indicated that contacts between B and T helper cells mediated by CD86 encourage signals for the proliferation and IgG secretion of normal B cells and B cell lymphomas. Recent study has revealed that CD86 also promotes the generation of a mature APC repertoire and promotes APC function and survival. CD86 has an important role in chronic hemodialysis; allergic pulmonary inflammation; arthritis; and antiviral responses; and thus is regarded as a promising candidate for immune therapy.

Activity: Immobilized human CD86 at 20 μg/ml (100 μl/well) can bind human CD28 with a linear ranger of 32-800 ng/ml.

Sequence: Met 1-His 239

Purity: > 97 % as determined by reducing SDS-PAGE.

Formulation: Lyophilized from sterile PBS, pH 7.4
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.

Reconstitution: Please refer to the printed manual for detailed information.

Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
