Introduction
Thrombopoietin is a glycoprotein hormone produced mainly by the liver and the kidney which regulates the production of platelets by the bone marrow. TPO stimulates the production as well as differentiation of megakaryocytes, the bone marrow cells which fragment into large numbers of platelets.
Description
TPO Human Recombinant produced in HEK293 cells is a single, glycosylated polypeptide chain containing 343 amino acids (22-353 a.a) and having a molecular mass of 36.8kDa.
TPO is fused to a 6 amino acid His-tag at C-terminus & purified by proprietary chromatographic techniques.
Source
HEK293 cells.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
TPO protein (0.25mg/ml) contains 10% glycerol and Phosphate-Buffered Saline (pH 7.4).
