WebA lag phase of 12 to 18 h, following growth at 30 degrees C, was required prior to administration of G418 to achieve maximal transformation frequency. Transformation frequencies ranged from 100 to 700 per micrograms of DNA and varied with the vector and strain used. The kanamycin gene imparted resistance to G418 in either the episomally or ... WebHowever, the model fails to predict the direction and intensity of selection in environments that fluctuate at moderate frequencies.
