IGFBP4 binds IGF1 and II, prolonging the half life of these growth factors and altering the way these growth factors interact with cells surface receptors.
  • 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: 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; specific activity is determined by the dose dependent inhibition of IGF-II induced proliferation of MCF-7 cells
