Gastrointestinal Permeability Assays

Our permeability studies use human gastrointestinal (GI) tissues which have a phenotypically accurate balance of drug-metabolizing enzymes and transporters. A typical experiment involves the application of a drug to the apical surface of the tissue, followed by periodic sampling of the Ussing chambers to measure the passage of drugs and any metabolites.
