Product Category | Recombinant Protein |
Target | Siglec-3/CD33 |
Synonyms | CD33 molecule; CD33; FLJ00391; gp67; Siglec3; Siglec-3; p67 |
Gene/Protein ID | P20138-1 |
Species | Human |
Exact Sequence | Asp18-His259 |
Molecular Weight | The protein has a predicted MW of 29.6 kDa. Due to glycosylation, the protein migrates to 52-60 kDa based on Tris-Bis PAGE result. |
Activity | Immobilized Human Siglec-3, His Tag at 0.5μg/ml (100μl/Well). Dose response curve for Anti-Siglec3 Ab., hFc Tag with the EC50 of 19.9ng/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. |
