Researchers devised a reversibly lockable DNA device for enclosing an enzyme and controlling its access to substrates. Turning on and off the activity of a single enzyme on demand is a much desired ...
Using Eppendorf BioSpectrometer for the determination of enzyme activity and substrate concentration
This article shows how enzymatic activity can be effectively determined by means of the Eppendorf BioSpectrometer. The preliminary measurements were carried out by utilizing the “single λ-continuous” ...
