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.
Human OX40 Ligand Trimer, His-Flag Tag immobilized on CM5 Chip can bind Human OX40, His Tag with an affinity constant of 0.98 μM as determined in SPR assay (Biacore T200).
The purity of Human OX40 is greater than 95% as determined by SEC HPLC.
Human OX40 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
