Assay Method Information

Assay Name:  Kinase Assay
Description:  Activated ERK1 and ERK2 activity was determined in a Mobility Shift Assay (MSA) format as follows: Compound and kinase solution were prepared with assay buffer (20 mM HEPES, 0.01% Triton X-100, 2 mM DTT, pH7.5) and mixed and incubated in for 30 mins at rt. ERK1 & ERK2 were then activated by the addition of F1-Substrate, ATP and metal solution and incubated for 1 h at rt. After 1 h, the reaction was terminated by the addition of 70 mL of Termination Buffer (QuickScout Screening Assist MSA; Carna Biosciences) to the well. The reaction mixture was applied to LabChip system (PerkinElmer), and the product and substrate peptide peaks were separated, analyzed and quantitated. The kinase reaction is evaluated by the product ratio calculated from peak heights of product (P) and substrate(S) peptides (P/(P+S)).
