Produktmerkmale: High Quality Authentic Human CD80 Protein

• The production of this recombinant, biotinylated CD80 protein is carried out using a proprietary expression platform.
• As expression hosts, the human HEK293 cells have a variety of advantages compared to other cell types.
• Most importantly, the proteins retain their authentic post-translational processing, which often translates into high bioactivity and stability.

High Bioactivity & Detection Sensitivity

• The bioactivity of biotinylated proteins is determined both by the structure of the protein itself, and by the way how biotinylation is performed.
• For every single protein, multiple options of tags and biotinylation methods are tested and the products are evaluated in a variety of binding assays.
• Only those with the best performance are selected for production.

Low Batch-to-Batch Variation

• Products are routinely tested using rigorous quality control measures to ensure consistent performance.
• Newly produced products are subjected to side-by-side comparison with our internal standard in a variety of assays.
• Only those within an acceptable margin of difference are allowed to be released.

Reinheit: >95 % as determined by SDS-PAGE.

Endotoxin-Niveau: Less than 1.0 EU per μg by the LAL method.

Ready-to-use AvitagTM biotinylated protein:
The product is exclusively produced using the AvitagTM technology. Briefly, a unique 15 amino acid peptide, the Avi tag, is introduced into the recombinant protein during expression vector construction. The single lysine residue in the Avi tag is enzymatically biotinylated by the E. Coli biotin ligase BirA.

This single-point enzymatic labeling technique brings many advantages for commonly used binding assays. The biotinylation happens on the lysine residue of Avi tag, and therefore does NOT interfere with the target protein's natural binding activities. In addition, when immobilized on an avidin-coated surface, the protein orientation is uniform because the position of the Avi tag in the protein is precisely controlled.

Hintergrund: B7-1 and B7-2, together with their receptors CD28 and CTLA-4, constitute one of the dominant co-stimulatory pathways that regulate T- and B-cell responses. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with a 20 - 100 fold higher affinity than CD28 and is involved in the down-regulation of the immune response. B-lymphocyte activation antigen B7-1 (referred to as B7) also known as cluster of Differentiation 80 (CD80), is a member of cell surface immunoglobulin superfamily and is expressed on activated B cells, activated T cells, macrophages and dendritic cells. It is the ligand for two different proteins on the T cell surface: CD28 (for autoregulation and intercellular association) and CTLA-4 (for attenuation of regulation and cellular disassociation). CD80 works in tandem with CD86 to prime T cells. CD80 plays a role in induction of innate immune responses by activating NF-κB-signaling pathway in macrophages. CD80 is thus regarded as promising therapeutic targets for autoimmune diseases and various carcinomas.
