Miniaturization of Cytochrome P450 Time-dependent Inhibition Screening Using the Echo® Liquid Handler
2 May 2013
As a large number of compounds are screened for ADMET properties against various cytochrome P450 (CYP) enzymes on a regular basis, miniaturization and automation of ADMET assays have become one of the top priorities to manage the cost and labor. This application note presents results from miniaturized time-dependent inhibition assays. The time-dependent inhibition for two of the most abundant CYP enzymes, CYP3A4 and 1A2, were evaluated. The results from the Echo liquid handler method demonstrate fast, reliable and accurate IC50 values.
