Split multi-well plate and methods

摘要

The invention provides exemplary testing devices, systems, and methods for evaluating the permeation of various chemicals through different types of cells. In one exemplary embodiment, a testing device is provided which comprises a plate defining at least one well having an open top end. At least one membrane is insertable into the well in a generally vertical orientation to divide the well into separate chambers. The membrane is removable from the well to allow the cells to be grown on the membrane before insertion into the well.
