Oncostatin M is a pleiotropic IL-6 family cytokine that signals through JAK/STAT, MAPK, and NF-κB pathways, making it central to studies of inflammation, hematopoiesis, and tumor microenvironment remodeling. This tag-free recombinant human OSM (residues 26–220) reproduces the mature secreted sequence and demonstrates high signaling potency, with an ED50 below 2 ng/mL in a TF-1 cell proliferation assay, corresponding to a specific activity exceeding 5.0 × 10⁵ IU/mg. Endotoxin levels below 1.0 EU/μg ensure that downstream immune cell responses—including STAT3 phosphorylation kinetics, macrophage activation, and primary cell differentiation assays—reflect genuine OSM-driven signaling rather than LPS-mediated artifacts. Purity above 97% by SDS-PAGE, combined with this stringent endotoxin profile, supports use as a functional reference standard in cytokine detection assays, a reliable positive control for ELISA and Western blot validation, and a defined stimulus in in vivo inflammation models.
