Growth factors and cytokines

Growth factors and cytokines are the unique cell signaling molecules that play important roles in cell proliferation and development. It's a fact that cell cultures can greatly benefit from the use of pure, high quality proteins.

To help ensure our products are of the highest quality, we've designed Gibco growth factors & cytokines with:

  • High biological activity—more results with less protein
  • High purity—minimized interference from proteins or other contaminants
  • Proven compatibility—Gibco proteins bioassayed with Gibco media
