Endotoxin Level: < 0.1 ng/μg of protein (<1EU/μg).
Biological Activity: Determined by its ability to stimulate the proliferation of human MO7e cells. The expected ED50 is ≤ 0.2 ng/ml, corresponding to a specific activity of ≥ 5 x 10^6 units/mg.
Reconstitution Instructions: 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 carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
Storage Temp.: -20°C
Shipping: Gel pack
Background Information: 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.
