一般描述
TPO (thrombopoietin) is a hematopoietic cytokine expressed in multiple tissue types. It is predominantly produced by liver and kidney and acts as a ligand for the cell surface receptor c-mpl.
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 murine 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.
生化/生理作用
TPO (thrombopoietin) is the key regulator of thrombopoiesis for platelet lineage. In both mice and humans, inactivation of this gene results in significant decrease in number of mature platelets produced by marrow progenitors. Transgenic mice with increased expression of this protein show progressive fibrosis and osteosclerosis of the bone marrow, as well as histological changes in kidneys, leading to mesangioproliferative glomerulopathy.

Lyophilized from 10 mM Sodium Phosphate, pH 8.0.
重悬
Centrifuge the vial prior to opening. Reconstitute in water to a concentration of ?0.5 mg/ml. Slow to dissolve. Do not vortex. This solution can be stored at 2-8℃ 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℃ to -80℃.
