TPO (Thrombopoietin, also known as Mpl-ligand, MGDF) stimulates the proliferation and maturation of megakaryocytes and promotes increased circulation levels of platelets in vivo. The murine TPO is a soluble 18.7kD protein containing 174 amino acid residues, which comprises the receptor binding domain of the Mpl-ligand protein.

Recombinant mouse Thrombopoietin expressed in E. coli.

Biological Activity:
The ED50 as determined by the dose-dependent stimulation of the proliferation of human MO7e cells is < 1.0ng/ml, corresponding to a specific activity of > 1x10e6 units/mg.

Storage and Stability:
Lyophilized powder may be stored at -20C. Stable for 12 months at -20C. Reconstitute with sterile ddH2O. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Aliquot to avoid repeated freezing and thawing. Store at -20C. Reconstituted product is stable for 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Molecular Weight:
Source: E. coli
Purity: ~98% (SDS-PAGE and HPLC). Endotoxin: 0.1ng/ug.
Form: Supplied as a lyophilized powder from 10mM Tris, pH 8.0. Reconstitute with sterile ddH20 to a concentration of 0.5-1mg/ml.
