Ideal for high or moderate throughput screening assays where cells are cultured on multiple permeable supports. Excellent for differentiation, toxicology, migration, and invasion studies. This assay platform consists of a 24-multiwell polyethylene terephthalate (PET) membrane insert plate with lid and either a media feeder tray or a polystyrene plate. Large, one-well feeder tray design enhances reproducibility from well to well and reduces the need for frequent media changes. Compatible with most robots and fluid handling instruments that accept Falcon® 24-well plate formats. Sterilized by gamma irradiation. For single use only.
