PhosphoSens EGFR Protein Kinase Assays, Substrates & Recombinant Enzymes
Continuous, real-time assays that directly quantify EGFR catalytic activity — generating a full progress curve in every well for IC₅₀, mechanism, and selectivity studies.
Real-time kinetic or TRF endpoint formats
Optimized substrates and assay-ready kits
Compatible with physiological ATP and cofactors
Designed for: drug discovery, lead optimization, and mechanistic kinase research teams
PhosphoSens-Kinetic assays directly quantify enzyme activity by continuously
monitoring substrate phosphorylation or dephosphorylation in real time,
generating a full progress curve in every well.
PhosphoSens-Red assays use europium-based time-resolved fluorescence detection
to enable robust, plate-based quantification of enzyme activity, making them
well suited for high-throughput screening workflows.
Wild-type and mutant forms of EGFR for assay development, kinase profiling, and mechanistic studies.
Enzymes are supplied active and optimized for PhosphoSens® substrates.

How many assays can I run per 1 mg of Sensor Peptide?
PhosphoSens Sensor Peptides range in molecular weight (MW) based on the size and sequence of the substrate. The average MW or a sensor peptide is 2,150 g/mol. This size Sensor Peptide will be re-suspended in approximately 450 µL of diluent. If running an assay in a 384-well plate, with a final well volume of 20 µL and Sensor Peptide concentration of 10 µM, you can run 2,250 assays!
How do I resuspend my lyophilized sensor peptide?
Reference the "Solubilization" section of the printed Certificate of Analysis (CofA) that is printed and shipped with every order. If you do not see this, please contact us at support@assayquant.com and we will share an electronic copy of your CofA.
