In cell motility assays:
a. Do we need to perform a cytotoxicity assay parallel with themotility assay? Why or why not?
b. If you know the IC50 value of the compound to be tested onthe motility assay, would you still need to perform thecytotoxicity assay? Why or why not?
c. Why do we use a DMSO control in cell-based drug assays? Forexample, do you need to include a DMSO control in every motilityassay? Why or why not?
