  • 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: to help ensure Gibco growth factors are of the highest quality, each protein is analyzed for purity along with structural homogeneity to get 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 stimulation of the proliferation of human MO7e cells
  • Proven compatibility: Gibco proteins are bioassayed with Gibco media
