Bulk substrate
AQT0505 PhosphoSens® Kinase Substrate
Bulk substrate for assay development, screening and high-throughput workflows. Kinase assay kits that include AQT0505 are on each target's assay page.
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 10 kinases simplifies selectivity and panel work
