Purity > 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Endotoxin Less than 1EU per _g by the LAL method.
Form Lyophilized
Shipping Shipped at ambient temperature.
Formulation Lyophilized from 0.22_m 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 _g/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.
The purity of Human CD89 is greater than 95% as determined by SEC-HPLC.
Human CD89 on Tris-Bis PAGE under reduced condition. The purity is greater than 95%.
