TPO/Thrombopoietin Protein, Mouse (335a.a, HEK293, C-His)

TPO/Thrombopoietin Protein, a lineage-specific cytokine, crucially regulates megakaryocyte proliferation and maturation, acting in the late stages of development from committed progenitor cells. Recognized as a major physiological regulator, TPO significantly influences circulating platelets, emphasizing its importance in the intricate process of platelet formation. TPO/Thrombopoietin Protein, Mouse (HEK293, C-His) is the recombinant mouse-derived TPO/Thrombopoietin protein, expressed by HEK293 , with C-6*His labeled tag.

Thrombopoietin (TPO), a lineage-specific cytokine, plays a crucial role in regulating the proliferation and maturation of megakaryocytes, acting at a late stage of their development from committed progenitor cells. Functioning as a key factor in megakaryopoiesis, TPO is recognized as a major physiological regulator of circulating platelets. Its influence on the later stages of megakaryocyte development underscores its significance in the intricate process of platelet formation.

Measured  in a cell proliferation assay using MO7e human megakaryocytic leukemic cells.  The ED₅₀ for this effect is 0.6746 ng/mL, corresponding to a specific  activity is 1.482×10⁶ units/mg.

  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM PB, 150 mM NaCl, 2 mM EDTA, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
