| Product Description | Recombinant Human B7-2/CD86 Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal.; It contains Leu26-Pro247. |
| Product Category | Recombinant Protein |
| Target | B7-2/CD86 |
| Synonyms | CD86 molecule; CD86; B70; B7-2 antigen; B72; B7-2; BU63; FUN-1; LAB72; MGC34413; CD28LG2 |
| Gene/Protein ID | P42081-1 |
| Species | Human |
| Exact Sequence | Leu26-Pro247 |
| Molecular Weight | The protein has a predicted MW of 28.2 kDa. Due to glycosylation, the protein migrates to 55-70 kDa based on Tris-Bis PAGE result. |
| Activity | Immobilized Human B7-2, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Human CTLA-4, hFc Tag with the EC50 of 0.12μg/ml determined by ELISA. See testing image for detail. |
| Product Tag | C-His-Avi |
| 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 (usually we use 1mg/ml solution for lyophilization). 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. |
