title: Development of an automated 7-day 96-well Caco-2 cell culture model.
abstract: Caco-2 cells are a widely accepted model to predict permeability and absorption of compounds in humans. We built up an automated 96-wellplate Caco-2 permeation model with reduced growth time. Model compounds (metoprolol, ketoprofen, verapamil, naproxen, hydrochlorthiazide), permeability markers (TEER, Lucifer Yellow, D-[1-(14)C]-mannitol) and confocal microscopy were used to assess the utility of our method on Biomek-FX-automation. The confocal imaging data showed that Caco-2 cells formed monolayers when cultured for 7 days with initial cell density of 2.1 x 10(5) cells/cm2. P-Glycoprotein was present in Caco-2 cells, localized on the plasma membrane. Permeation of model compounds was comparable to those obtained from traditional 12-wellplate experiments.
