A new limit in protein complex stability

Unique Thermal & Chemical Stability of the ChromoTek GFP-Binding Protein:GFP Complex

An affinity binder that binds a protein tag even in 8 M urea, 3 M Guanidinium Hydrochloride, or at 83°C? That is the ChromoTek GFP-binding protein. The GFP-binding protein:GFP is a complex you can hardly break.

Imagine what such a stable protein-protein complex means for your research:

  • Protein interaction analysis
  • Immunoprecipitation
  • Immunofluorescence
