  • Patent number: 6489094
    Abstract: A method and device for the automated large scale preparation for testing of drug-drug interactions, particularly with determination of IC50 and Ki, as a screening tool enhancement for determining viability of large numbers of compounds as drug candidates. Small samples of specific probe substrates and new compound inhibitors are automatically dispensed en masse into multi-welled reaction plates which are prefilled with thawed human microsomes, buffer and cofactor. The reaction plates are incubated and the reaction products are tested within degradation time limits, for initial biological determinations of relevant interaction effects of the compounds.
