Assay Method Information

Assay Name:  In Vitro Assay
Description:  Test compounds (from DMSO stock solutions) were added to (final concentrations) 20 ug/ml enzyme solution (human, mouse or rat recombinant CSE) plus 50 uM PLP in assay buffer (100 mM potassium phosphate pH 7.6) in 96 well plates in total volume of 190 ul. Plates were incubated for 30 minutes at room temperature before the addition of 10 ul of 200 mM (20× final in assay buffer) DL-Homocysteine substrate to each well. Plates were incubated at 37 C for 3 hours. 50 ul 20 mM DMPDA in 7.2N HCl was added to each well followed by 50 ul 30 mM FeCl3 in 1.2N HCl. Plates were incubated for 10 minutes with shaking at room temperature and then absorbance at 671 nm read in Promega GloMax microplate reader.
