| Product Category | Recombinant Protein |
| Target | B7-1/CD80 |
| Synonyms | CD80 molecule; B7; B71; B7-1; BB1; CD28LG1; CD80; B7.1; CD28LG1; LAB7 |
| Gene/Protein ID | P33681-1 |
| Species | Human |
| Exact Sequence | Val35-Asn242 |
| Molecular Weight | The protein has a predicted MW of 50.5 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Tris-Bis PAGE result. |
| Activity | Immobilized Human B7-1, hFc Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human CTLA-4, His Tag with the EC50 of 0.27μg/ml determined by ELISA. See testing image for detail. |
| Product Tag | C-hFc |
| Express System | Expi293 |
| Purity | > 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC |
| Endotoxin | Less than 1EU per μg by the LAL method. |
| Form | Lyophilized |
| Shipping | Shipped at ambient temperature. |
| Formulation | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
| Reconstitution | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water. |
| Stability And Storage | Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. |
