CIM-Plates 16 are single use, disposable devices used for performing cell invasion and cell migration assays on the RTCA DP Instrument. The CIM-Plate 16 comprises a plate cover (lid), an upper chamber and a lower chamber. The upper chamber has 16 wells that are sealed at the bottom with a microporous polyethylene terephthalate (PET) membrane containing microfabricated gold electrode arrays on the bottom side of the membrane. The median pore size of this membrane is 8 μm. The lower chamber has 16 wells, each of which serves as a reservoir for media and any chemo attractant for the cells in corresponding upper chamber wells.
