TNF-α drives NF-κB and MAPK signaling cascades central to inflammation, apoptosis, and tumor microenvironment remodeling, making precise functional activity essential for meaningful in vitro results. This tag-free recombinant human TNF-α (residues 77–233) demonstrates an ED50 of 10–50 pg/mL in the L-929/actinomycin D cytotoxicity assay, confirming potent bioactivity suitable for apoptosis induction studies, NF-κB pathway activation experiments, and use as a reference standard in cytokine detection assays. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts, which supports use in primary immune cell activation assays, macrophage polarization studies, and in vivo tumor biology models where confounding innate immune stimulation must be excluded. Purity exceeding 95% by SDS-PAGE, combined with this stringent endotoxin control, satisfies the criteria typical for antibody development workflows including immunization, ELISA coating, and functional blocking assays.
