Binding
Biochemical EGFR Inhibition Assays (5 mM ATP): 5 μL of EGFR enzyme form in assay buffer (50 mM HEPES pH 7.3, 10 mM MgCl2, 1 mM EGTA, 0.01% Tween 20, 2 mM DTT) are dispensed into columns 1-23, than 5 μL of ATP and ULight-poly-GT substrate (PerkinElmer; TRF0100-M) mix in assay buffer is added to all wells (final assay concentration of the ULight-poly-GT substrate 200 nM). Each of the different EGFR enzyme form assays is available at low ATP (final assay concentration 5 μM). After 90 minutes incubation at room temperature 5 μL EDTA (final assay concentration 50 mM) and LANCE Eu-anti-P-Tyr (PT66) antibody (PerkinElmer, AD0069) (final assay concentration 6 nM) mix are added to stop the reaction and start the binding of the antibody. After additional 60 minutes incubation at room temperature the signal is measured in a PerkinElmer Envision HTS Multilabel Reader using the TR-FRET LANCE Ultra specs of PerkinElmer (used wavelengths: excitation 320 nm, emission 1 665 nm, emission 2 615 nm). Each plate contains 16 wells of a negative control (diluted DMSO instead of test compound; w EGFR enzyme form; column 23) and 16 wells of a positive control (diluted DMSO instead of test compound; w/o EGFR enzyme form; column 24). Negative and positive control values are used for normalization and IC50 values are calculated and analysed using a 4 parametric logistic model.
