| Biochem/physiol Actions: | Thrombopoietin (TPO) stimulates the proliferation and maturation of megakaryocytes, and promotes increased circulating levels of platelets in vivo. TPO signals through the cellular proto-oncogene (c-mpl) receptor and acts as an important regulator of circulating platelets. High levels of TPO have been observed in patients with aplastic anemia. Human and murine TPO exhibits cross-species reactivity. |
| General description: | Thrombopoietin (TPO) is a lineage specific growth factor, produced in the liver, kidney and skeletal muscle. It is an acidic glycoprotein. The gene encoding it is localized on human chromosome 3q27.1. Recombinant human TPO is a fully biologically active 174 amino acid polypeptide (18.6kDa), which contains the erythropoietin-like domain of the full length TPO protein. |
| Physical form: | Lyophilized from 0.1% TFA. |
| Reconstitution: | Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a stabilizer (example 5% Trehalose) and store in working aliquots at -20°C to -80°C. |
