Our Gibco growth factors and Invitrogen recombinant proteins are produced in a range of expression systems including mammalian, E. coli, insect, and baculovirus to meet different cell culture application needs. Offering proven compatibility with Gibco cell culture media, these growth factors and recombinant proteins are designed to deliver superior results with less protein and with minimized interference from proteins or other contaminants.
TNF Recombinant Human Protein (Gibco™)
• High purity—no interference from other proteins or contaminants
• High biological activity—more results with less protein
• Proven compatibility—Gibco® proteins bioassayed with Gibco® media
High Purity Recombinant Bioactive Protein
Recombinant Human Tumor Necrosis Factor-α is one of our more than 250 available Gibco® recombinant proteins. To help ensure Gibco® growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to ensure a biologically active protein.
High Biological Activity
In-house activity testing of Gibco® Recombinant Proteins includes cell proliferation, cytotoxicity, chemotaxis, calcium flux, secondary cytokine up-regulation, induction of surface antigen expression, antiviral, and protease assays. Recombinant Human Tumor Necrosis Factor-α (TNF) specific activity is determined by the dose dependent cytotoxic effect on L929 cells in the presence of actinomycin D.
Gibco® proteins are bioassayed with Gibco® media. Since 1962, Gibco® has been the consistent provider of high quality media, reagents, and sera for reliable cell culture.
