Assay Method Information

Assay Name:  LanthaScreen Activity Assay
Description:  Kinase reactions were carried out at room temperature with the following components: 1× kinase reaction buffer, 5 μg/mL (40 nM) Mps1 kinase, 200 nM AF-647 E4Y substrate, and 1 μM ATP (Km,app<1 μM). After one hour a preparation of EDTA (20 mM) and Eu-PY20 Tb-labeled antibody (4 nM) in TR-FRET dilution buffer was added. The final concentration of EDTA and Eu-PY20 in the reaction mixture is 10 mM and 2 nM respectively. The reaction mixture was incubated at room temperature for 30 minutes before being read on a plate reader configured for LanthaScreen TR-FRET.
