• Material Safety Data Sheets (MSDS)

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.

Cd86

Human Cells

A DNA sequence encoding the extracellular domain (Met 1-Glu 245) of mouse CD86 (NP_062261.3) precursor was fused with a polyhistidine tag at the C-terminus.

Mouse

The recombinant mouse CD86 consists of 233 amino acids after removal of the signal peptide and has a predicted molecular mass of 26.8 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm CD86 is approximately 40-55 kDa due to glycosylation.

> 92 % as determined by SDS-PAGE

Measured by its binding ability in a functional ELISA. Immobilized mouse CD86 at 20 μg/ml (100 μl/well) can bind mouse CD28 with a linear ranger of 6.4-800 ng/ml.
