Assay principle

  • GFP-tagged human p53 is anchored at a specific location in the nucleus of  F2H cells, forming a bright fluorescent spot in the green channel.
  • Interaction with the RFP-tagged human Mdm2 or the RFP-tagged human Mdm4 can be easily evaluated by conventional fluorescence microscopy as enrichment of red fluorescence at the location of the green spot.
  • Compounds’ ability to disrupt the p53 and Mdm2 interaction or the p53 and Mdm4 interaction is determined based on the disappearance of the red spots from the anchored green spots.


F2H allows direct side-by-side comparison of the compound's activity and kinetics in live cells.
