Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using bovine EJG cells is less than 2.0μg/ml, corresponding to a specific activity of >500IU/mg.
Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation
Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4, 0.02% Tween-20.
Endotoxin
Less than 0.1EU/μg of rHuEG-VEGF as determined by LAL method.
Reconstitution
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions.
