- the LanthaScreen Eu kinase inhibition assay uses an Alexa Fluor TM marker that binds to a kinase and is detected by adding an Eu-labeled antibody. Binding of the marker and the antibody to the kinase results in a high degree of FRET, whereas displacement of the marker by an inhibitor results in a loss of FRET. Unlike many other kinase activity assays, this is a simple mix-read assay, with no development steps. This test method has been developed by "Life Technologies" and they identify competitive ATP kinase inhibitors, making them suitable for the detection of any compound that binds to the ATP site.
