WebIf you are using ampicillin for selection in your expression experiments, you may be experiencing plasmid instability due to the absence of selective conditions. This occurs as the ampicillin is destroyed by β-lactamase or hydrolyzed under the acidic media conditions generated by bacterial metabolism. WebThe use of media containing ampicillin allows for the selection of successful transformants, however it is only when the sugar arabinose is also added to the media that it will be possible to observe the bright green fluorescence. This is because the GFP protein is under the control of an arabinose operon. howard miller grandfather clock 611005WebAmpicillin is an antibiotic, normally E. Colicannot survive in its presence.
