F2H Kit Androgen Receptor

Analyze and manipulate the intramolecular interaction between the N- and C-terminal domains of Androgen Receptor (AR) with ChromoTek Fluorescent-Two Hybrid (F2H®) AR.
Wild-type (wt), as well as several mutant AR forms can be investigated.

AR is expressed as two separate domains
Bait:    AR ligand binding domain (AR-LBD) fused to GFP
Prey:   AR N-terminal domain (AR-NTD) fused to RFP
Bait and prey interact.

Detect early steps of Androgen Receptor activation
Real-time agonists and antagonists screening
Visualized in live mammalian cells

Available AR variants
AR-LBD: wt, W741L, F876L, T877A, F876L-T877A

  • AR is expressed as two separate domains: AR-LBD (ligand binding domain), comprising the AR’s C-terminus, either wt or mut, fused to GFP: AR-LBD-GFP
  • AR-NTD (N-terminal domain), comprising the AR’s N-terminus, fused to RFP: AR-NTD-RFP
  • F2H BHK cells express components of the protein-protein interaction platform, which recruits GFP-tagged AR-LBD to a specific location in the nucleus
  • AR-LBD-GFP and AR-NTD-RFP constructs are co-transfected into the F2H BHK cells
  • AR-LBD-GFP forms a bright green spot at the specific location in the nuclei whereas AR-NTD-RFP is diffusely distributed in the nucleus
  • Upon stimulation by an agonist (e.g. DHT), immobilized AR-LBD-GFP undergoes a conformation change and recruits AR-NTD-RFP: AR-NTD-RFP forms a bright red spot superimposed with the green spot.


Green spot is present, red spot is absent => assay works: no interaction
Green spot is present, red spot is present at the same location => assay works: interaction

Reversible screening:
The F2H AR assay is fully reversible: the AR wt interaction can be induced by an agonist (e.g. 0.25 nM DHT) and then subsequently disrupted by addition of a potent antagonist (e.g. 10 µM bicalutamide).

About Androgen Receptor

The human Androgen receptor (AR) is an important target for developing drug therapies combating prostate cancer. The very early event in AR activation, namely the intramolecular interaction between the N- and C-terminus of AR, is very important.
