Thrombopoeitin Recombinant Protein

TPO is a lineage specific growth factor, produced in the liver, kidney and skeletal muscle. It stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals through the c-mpl receptor and acts as an important regulator of circulating platelets. Human and murine TPO exhibits cross-species reactivity. Recombinant rat TPO is a fully biologically active 174 amino acid polypeptide (18.7 kDa), which contains the erythropoietin-like domain of the full length TPO protein.

The lyophilized Thrombopoeitin recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted Thrombopoeitin is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing Thrombopoeitin recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
