| Molecular Weight | The protein has a predicted MW of 16.9 kDa. Due to glycosylation, the protein migrates to 20-25 kDa based on Tris-Bis PAGE result. |
| Activity | Immobilized Human IL-31, His Tag at 5ug/ml (100ul/Well) on the plate. Dose response curve for Human IL-31 RA, hFc Tag with the EC50 of 1.15ug/ml determined by ELISA (QC Test). The affinity constant of 1.5nM as determined in SPR assay (Biacore T200). See testing image for detail. |
| Product Tag | N-His |
| 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 5% 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. |
