Presentation Title: “Bridging Biochemistry and Biology: Continuous Kinase Activity Assays with Complex Samples”
Kinase inhibitors are central to modern therapeutics, yet early discovery often relies on assays with limited mechanistic or physiological insight—creating a disconnect between biochemical results and biological complexity. To address this limitation, we have developed continuous fluorescence-based assays that directly quantify kinase activity in crude lysates and tissue homogenates. By delivering real-time insights under more physiological conditions, these assays help identify more effective drugs earlier to improve translational success with patients.
Would you like to have our CSO give you a presentation of how we enable real-time enzymology of kinase activity in complex cell lysate matrices?
See Why Continuous Assays Reveal What Endpoint Assays Miss
Continuous enzymatic assays offer higher accuracy and precision and enable rapid identification and detailed kinetic characterization of time-dependent inhibition—capturing residence times and inactivation efficiencies that endpoint assays cannot.

Study Kinase Enzyme Activity Where Biology Happens
Most kinase assays overlook biological complexity.
To address this challenge in protein kinase inhibitor (PKI) development, we designed a kinase activity assay that delivers mechanistic insight and biological relevance.
