Validation Data Gallery

  • Purity of recombinant human OSM was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

  • Recombinant human OSM (HZ-1030) stimulates dose-dependent proliferation of the TF-1 human erythroleukemic indicator cell line. Cell number was quantitatively assessed by PrestoBlue® Cell Viability Reagent. TF-1 cells were treated with increasing concentrations of GMP recombinant OSM for 96 hours. The EC50 was determined using a 4-parameter non-linear regression model. The EC50 range is 0.1-1.5 ng/mL​.

Background

Oncostatin M (OSM) is a member of a cytokine family that includes a leukemia-inhibitory factor, granulocyte colony-stimulating factor, and interleukin 6. OSM is a growth regulator which inhibits the proliferation of some tumor cell lines. It can stimulate proliferation of AIDS-KS cells. It regulates cytokine production, including IL-6, G-CSF, and GM-CSF from endothelial cells. OSM is involved in the maturation of fetal hepatocytes, thereby promoting liver development and regeneration (PMID: 9133674; 29526757; 29363180; 21887386).
