In most electrophoresis units, the gel is mounted between two buffer chambers in such a way that the only electrical connection between the Destain the gel until the bands are properly seen. Cyclic AMP (final concentration 20 μM) was added to the electrophoresis running buffer. The goal of this technique is to separate a mixed sample of proteins to identify and quantify single proteins from the mixture. Application of a constant electric field causes DNA fragments (all have a uniform, strong negative charge) to migrate toward the cathode. Nowadays either an agarose gel or polyacrylamide gels are used.
