Cell Migration and Invasion Assays by Platypus Technologies In order to ensure consistent cell-free regions for each experiment, Cell Migration and Invasion Assays by Platypus Technologies utilize exclusion zone technology. The Oris™ Cell Migration and Invasion Assays allow the reproducible and accurate quantification of cell movement. Cell Migration Assays No artificial membranes Industry-standard 96- or 384-well formats Image Credit: Platypus Technologies, LLC In order to form a central cell-free detection zone in the center of every well of a 96-well plate, Oris™ Cell Migration assays utilize physical “stopper” barriers. Utilize Oris™ for maximal flexibility in assay design. Utilize Oris™ with the Oris™ Detection Mask for analysis on plate readers that lack virtual masking.
