Fluctuation assay. A modification of the original Luria-Delbruck fluctuation assay using small-volume cultures in 96-well plates.
Fitness assay Assay for measuring relative growth rate using a fluorescently-labeled reference strain.
Competitive mating assay Analogous to the Fitness Assay, this assay measures the relative mating ability. Although described for drug-marked strains, this protocol would be best with fluorescently-labeled strains.
