EastMab BioTag-free Human TNF-alpha Recombinant Protein with high purity, potent NF-kB bioactivity, and low endotoxin levels for inflammation and cytokine signaling research.
Human TNF-alpha Recombinant Protein is a high-purity, biologically active cytokine produced in an E. coli expression system and designed for advanced immunology, inflammation, oncology, and cell signaling research.
This recombinant protein is tag free and corresponds to the biologically relevant region Ser113–Ala271 of human TNF-alpha.
Each lot is validated for strong bioactivity using an NF-kB reporter gene assay, ensuring consistent performance in cell-based functional studies. With low endotoxin levels and high purity verified by SDS-PAGE under both reducing and non-reducing conditions, this protein is suitable for sensitive in vitro applications requiring reliable cytokine activity.
Ideal for studies involving inflammatory signaling, immune regulation, apoptosis, cytokine networks, and therapeutic target discovery.
