CD86 Protein, Human, Recombinant (His & Fc Tag): 产品信息
> 95 % as determined by SDS-PAGE
< 1.0 EU per μg of the protein as determined by the LAL method
1. Measured by its ability to bind human CD28 in a functional ELISA. 2. Measured by its ability to induce IL2 secretion by Jurkat human acute T cell leukemia cells. The ED50 for this effect is 1-5μg/mL.
A DNA sequence encoding the extracellular domain (Met 1-His 239) of human B7-2 (NP_008820.2) pro-protein was fused with the C-terminal His-tagged Fc region of human IgG1 at the C-terminus.
The recombinant human B7-2/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 467 amino acids and has a predicted molecular mass of 53.2 kDa. In SDS-PAGE, the apparent molecular mass of rh B7-2/Fc monomer is approximately 80-90 kDa due to glycosylation.
Lyophilized from sterile PBS, pH 7.4 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. 2. Please contact us for any concerns or special requirements.
Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃ Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

CD86, also known as B-lymphocyte activation antigen B7-2 (referred to as B7), 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.
