    Handling Advice

    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.

    Storage

    -20 °C

    Storage Comment

    The 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.

    Expiry Date

    24 months
  • Target

    Thrombopoietin (THPO)

    Background

    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.
