Recombinant Human CD86 protein, C-His-hFc Tag
Product Description
Cat
IMP-393
Official Symbol
CD86
Product Overview
Recombinant Human CD86 protein (NP_008820.2) (Met 1-His 239) pro-protein was expressed in HEK293, fused with the C-terminal His-tagged Fc region of human IgG1 at the C-terminus.
Description
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. A 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.
Expression System
HEK293
Species
Human
Tag
C-His-hFc Tag
Predicted N Terminal
Leu 20
Form
Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Molecular Mass
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.
Protein length
Met 1-His 239
Endotoxin
< 1.0 EU per μg of the protein as determined by the LAL method
Purity
> 95 % as determined by SDS-PAGE
Storage
Samples are stable for up to twelve months from date of receipt at -20°C to -80°C. Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
