Cynomolgus B7-1/CD80 Protein
Recombinant Cynomolgus B7-1/CD80 Protein is expressed from HEK293 with hFc tag at the C-terminus. It contains Val35-Asn242.[Accession | G7NXN7]
The protein has a predicted MW of 49.84 kDa. Due to glycosylation, the protein migrates to 60-80 kDa based on Tris-Bis PAGE result.
Less than 1EU per μg by the LAL method.
> 95% as determined by Tris-Bis PAGE
> 95% as determined by HPLC
Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
-20 to -80°C for 12 months as supplied from date of receipt.
-80°C for 3-6 months after reconstitution.
2-8°C for 2-7 days after reconstitution.
Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Cynomolgus B7-1 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
The purity of Cynomolgus B7-1 is greater than 95% as determined by SEC-HPLC.
Immobilized Cynomolgus CTLA-4, His Tag at 0.5μg/ml (100μl/well) on the plate. Dose response curve for Cynomolgus B7-1, hFc Tag with the EC50 of 12.3ng/ml determined by ELISA.
Cluster of differentiation 80 (also CD80 and B7-1) is a protein found on dendritic cells, activated B cells and monocytes that provides a costimulatory signal necessary for T cell activation and survival. It is the ligand for two different proteins on the T cell surface: CD28 and CTLA-4.
