Approximately 20.5 kDa, a disulfide-linked homodimer of two 96 amino acid polypeptide chains.
Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using human TT medullary thyroid cancer cells is less than 10 ng/ml, corresponding to a specific activity of > 1.0 × 105 IU/mg.
Sterile Filtered White lyophilized (freeze-dried) powder.
Lyophilized from a 0.2 um filtered concentrated solution in PBS, pH 7.4.
Less than 0.1 EU/ug of rHuPersephin as determined by LAL method.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 4 mM HCl 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.
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.
> 97 % by SDS-PAGE and HPLC analyses.
