| Molecular Weight | The protein has a predicted MW of 72.7 kDa. Due to glycosylation, the protein migrates to 80-110 kDa based on Tris-Bis PAGE result. |
| Activity | Immobilized Human Her4 at 1ug/ml (100ul/well) on the plate. Dose response curve for Human NRG1 Beta 1, hFc Tag with the EC50 of 34.7ng/ml determined by ELISA. See testing image for detail. |
| Product Tag | C-His-Avi |
| Express System | HEK293 |
| Endotoxin | Less than 1EU per ug by the LAL method. |
Shipping, Reconstitution & Storage
| Form | Lyophilized |
| Shipping | Shipped at ambient temperature. |
| Formulation | Lyophilized from 0.22um 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 ug/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. |
