PulseFieldElectrophoresis
Manipulating and analyzing DNA are fundamentals in the field of molecular biology. Indeed, separating complex mixtures of DNA into different sized fragments by electrophoresis was a well-established technique by the early 1970's.Typically, DNA was isolated intact and then treated with restriction enzymes to generate pieces small enough to resolve by electrophoresis in agarose or acrylamide. Although this procedur......阅读全文
