| Description: | HIF-PHD2 activity was measured using homogeneous TR-FRET technology (see also, US2008/004817; Dao J H et al., Anal Biochem. 2009, 384:213-23). To each well of a 1/2 Area 96-well plate was added 2 μL of test compound in DMSO and 40 μL of assay buffer (50 mM Tris PH7.4/0.01% Tween-20/0.1 mg/ml BSA/1 mM Sodium ascorbate/20 μg/ml Catalase/10 μM FeSO4) containing 600 nM full length PHD2. After a 30 min preincubation at room temperature, the enzymatic reactions were initiated by the addition of 8 μL of substrates (final concentrations of 0.2 μM 2-oxoglutarate and 0.5 μM HIF-1α peptide biotinyl-DLDLEMLAPYIPMDDDFQL). After 2 hr at room temperature, the reactions were terminated and signals were developed by the addition of a 50 μL quench/detection mix to a final concentration of 1 mM ortho-phenanthroline, 0.1 mM EDTA, 0.5 nM anti-(His)6LANCE reagent, 100 nM AF647-labeled Streptavidin, and 30 nM (His)6-VHL-elonginB-elonginC complex. |
