Recombinant Human Fibroblast Growth Factor 4 (FGF4) is a bioactive protein intended for use in cell culture applications. FGF4 is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities and are involved in a variety of biological processes including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. Studies on the mouse homolog suggest a function in bone morphogenesis and limb development through the sonic hedgehog (SHH) signaling pathway.
• 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 Fibroblast Growth Factor 4 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 Fibroblast Growth Factor 4 (FGF4) specific activity is determined by the dose dependent stimulation of thymidine uptake by BaF3 cells expressing FGF-receptors.
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.
