ActoFactor™ Recombinant Rat Thrombopoietin

  • Specification
  • Recommended Products
Cat.No.
CSC-CTK0847
Description
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.

E.coli
Purity
Greater than 98% as determined by HPLC and SDS-PAGE analysis.
Activity
The ED50 as determined by the dose-dependent stimulation of the proliferation of human MO7e cells was found to be ≤ 0.2 ng/ml, corresponding to a specific activity of Greater than 5 x 10^6 units/mg.
Endotoxin Level
Less than 1 EU/μg.
Formulation
Lyophilized from a sterile-filtered protein solution in sodium citrate (pH 4.5).
Reconstitution
Please centrifuge product briefly before opening vial. The lyophilized protein should be reconstituted in sterile, ultra-pure water to a concentration of 0.1 - 1.0 mg/ml. This solution can then be diluted into other aqueous buffers and stored at -20°C for future use.
Storage & Stability
The lyophilized protein, though stable at room temperature for up to 3 weeks, is best stored desiccated at -20°C. Reconstituted protein should be used immediately or stored long-term in undiluted working aliquots at -20°C. Avoid repeated freeze-thaw cycles.
