Flow Magnetic Tweezers: Gyrase dynamics in absence of drug Ciprofloxacin

The video contains a whole field from a force spectroscopy experiment called Flow Magnetic Tweezers (FMT). It shows E. coli DNA Gyrase manipulating DNA topology by relaxing positive and introducing negative coils in absence of Ciprofloxacin, reaction of Gyrase to external torque and eventual wash with SDS.
