Purity:> 98 % by SDS-PAGE and HPLC analyses.
Biological Activity:Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using bovine EJG cells is less than 2.0 μg/ml, corresponding to a specific activity of > 500 IU/mg.
Physical Appearance:Sterile Filtered White lyophilized (freeze-dried) powder.
Formulation:Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, 0.02 % Tween-20.
Endotoxin:Less than 0.1 EU/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 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.
Stability & Storage:Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- 12 months from date of receipt, -20 to -70 °C as supplied.
- 1 month, 2 to 8 °C under sterile conditions after reconstitution.
- 3 months, -20 to -70 °C under sterile conditions after reconstitution.
