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 8% 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.
Biotinylated Human IL-18 R1, His Tag captured on CM5-SA Chip can bind Human IL-18, No Tag with an affinity constant of 1.4nM as determined in SPR assay (Biacore T200).
