F2H®-Kit Basic for effortless imaging of interactions between GFP- and RFP-tagged proteins of interest and domains thereof in live mammalian cells.

The Fluorescent Two- Hybrid (F2H®) Technology is a fast and simple way to study protein-protein interactions (PPIs) by conventional fluorescence microscopy. Its direct optical readout is optimal for high-content analysis (HCA) and screening for PPI inhibitors.


F2H® Principle:

  • F2H® cells (BHK origin) carry a GFP-anchoring platform in the nucleus
  • GFP- and RFP-fusion proteins (bait and prey) are transiently expressed in F2H® cells
  • GFP-bait is recruited to the platform → bright green spot
  • If RFP-prey interacts with the bait → red fluorescent spot co-localizes with the green spot
  • If RFP-prey does not interact with the bait → no red spot, disperse red fluorescence
