Recombinant Human Insulin-like Growth Factor Binding Protein 4 (IGFBP4) is a bioactive protein intended for use in cell culture applications. IGFBP4 binds IGF1 and II, prolonging these growth factors' half life and altering the way these growth factors interact with cells surface receptors. This is the 100 microgram size.

• High purity—Minimizes 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 Insulin-like Growth Factor Binding Protein 4 (IGFBP4) 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 help ensure a biologically active protein.

High Biological Activity
In-house activity testing of Gibco® Recombinant Proteins includes cell proliferation, cytotaxis, calcium flux, secondary cytokine up-regulation, induction of surface antigen expression, and protease assays. Recombinant Human Insulin-like Growth Factor Binding Protein 4 (IGFBP4) specific activity is determined the dose dependent inhibition of IGF-II induced proliferation of MCF-7 cells.

Proven Compatibility
Gibco® proteins are bioassayed with Gibco® media. Since 1962, Gibco® has been a consistent provider of high quality media, reagents, and sera for reliable cell culture.
