Active Recombinant Human OSM Protein (228 aa)

• Cat.No.: OSM-321O
• Product Overview: Recombinant human Oncostatin M (rhOSM) produced in E. coli is a single non-glycosylated polypeptide chain containing 228 amino acids. A fully biologically active molecule, rhOSM has a molecular mass of 25.9 kDa analyzed by reducing SDS-PAGE and is obtained by proprietary chromatographic techniques.

Specification

• Description: Oncostatin M (OSM) is a multifunctional cytokine, and belongs to Interleukin-6 (IL-6) subfamily, including IL-11, leukemia inhibitory factor (LIF), ciliary neurotropic factor, cardiotrophin-1, and novel neurotropin-1. In vivo, OSM is secreted from activated T cells, monocytes, neutrophils, and endothelial cells. OSM is related to LIF, and share a receptor with LIF in human. Human OSM can bind to gp130 and recruit OSM Receptor β or LIF Receptor β to form a ternary complex. OSM stimulates the growth of different types of cells, including megakaryocytes, fibroblasts, vascular endothelial cells, and T cells. On the other hand, OSM inhibits the proliferation of several cancer cell lines, such as solid tissue tumor cells, lung cancer cells, melanoma cells, and breast cancer cells.
