| Summary |  | 
| Source |  | 
| Molecular Weight | Approximately 7.5 kDa, a single non-glycosylated polypeptide chain containing 67 amino acids. | 
| Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using serum free human MCF-7 cells is less than 2 ng/ml, corresponding to a specific activity of > 5.0 × 105 IU/mg. | 
| Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | 
| Formulation | Lyophilized from a 0.2 um filtered concentrated solution in 20 mM Tris-HCl, pH 8.0, 150 mM NaCl, with 0.02 % Tween-20. | 
| Endotoxin | Less than 1 EU/ug of rHuIGF-2 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 and 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. |
