Determination of Cellular Localization of Expression of Flavin-Containing Monooxygenase Genes in Mou

Methods are described for the cellular localization of expression of flavin-containing monooxygenase (FMO) genes in various mouse tissues by in situ hybridization. These include the production of digoxigenin (DIG)-labeled antisense and sense RNA probes by transcription from FMO cDNA templates, the preparation of paraffin wax-embedded and cryostat tissue sections, the hybridization of RNA probes to tissue sections, and the specific detection of hybridized probes using an antibody to DIG.
