Continuous, real-time assays that directly quantify FGFR3 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.
