How PhosphoSens® substrates work

PhosphoSens® substrates are peptides carrying an environment-sensitive fluorophore next to the phospho-acceptor residue. When the kinase transfers a phosphate to the substrate, fluorescence increases, so activity is read continuously and directly in a plate reader.

  • Real-time progress curves, not single end-points
  • Run at physiologically relevant ATP concentrations
  • No antibodies, coupling enzymes, wash steps or radioactivity
  • One substrate across 2 kinases simplifies selectivity and panel work
