Biological Activity
The ED50 as determined by the dose-dependant stimulation of MO7e cells is < 0.8 ng/ml, corresponding to a specific activity of 1.25MUnits/mg.

Description
Thrombopoietin Human Recombinant produced in E.Coli is a single, non-glycosylated soluble polypeptide chain containing 174 amino acids and having a molecular mass of 18608 Dalton which comprises the receptor binding domain of the Mpl-ligand protein.
The TPO is purified by proprietary chromatographic techniques.

Formulation
Lyophilized from a concentrated (1mg/ml) solution containing 10mM sodium phosphate pH-8.

Physical Appearance
Sterile Filtered White lyophilized (freeze-dried) powder.

Purity
Greater than 85.0% as determined by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized Thrombopoietin in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source
Escherichia Coli.

Stability
Lyophilized Thrombopoietin although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution TPO Human should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
