Optimize with multiple high-throughput assay formats

Thermo Fisher Scientific offers four high-throughput assay technologies for your biochemical kinase research.

  • LanthaScreen Eu Kinase Binding Assays—Obtain sensitive detection of kinase inhibitors, including allosterics; interrogate active and non-activated kinases; track slow-binding inhibitors in real time, and compare inhibitor on-off rates with this robust assay technology.
  • LanthaScreen Kinase Activity Assays—A powerful toolbox for TR-FRET kinase activity assay development – choose exactly the reagents you need and acquire high quality data with minimal assay interference.
  • Adapta Universal Kinase Assays—A universal TR-FRET assay suitable for all kinases; including difficult-to-assay targets such as lipid kinases.
  • Z´-LYTE Kinase Assay—An ideal assay for secondary screening, hit validation and profiling, Z’-LYTE is the primary assay technology utilized in our SelectScreen Kinase Profiling Service.
