| Product Description | Recombinant Human CD21 Protein is expressed from Expi293 with His tag at the C-terminal.It contains Ile21-Arg971. |
| Product Category | Recombinant Protein |
| Target | CD21 |
| Synonyms | EBV receptor; CD21; C3DR; CR2; C3DRSLEB9; CVID7; SLEB9 |
| Gene/Protein ID | P20023-1 |
| Species | Human |
| Exact Sequence | Ile21-Arg971 |
| Molecular Weight | The protein has a predicted MW of 105.3 kDa. Due to glycosylation, the protein migrates to 110-130 kDa based on Bis-Tris PAGE result. |
| Activity | Immobilized Human CD21, His Tag at 0.5μg/ml (100μl/Well) on the plate. Dose response curve for Anti-CD21 Antibody, hFc Tag with the EC50 of 7.9ng/ml determined by ELISA. See testing image for detail. |
| Product Tag | C-His |
| 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 8% 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. |
