DNA is the foundation of life--and of your life's work. The application of many molecular biological techniques in the modern laboratory rests on the ability to isolate pure populations of plasmid DNA and pure, high molecular weight genomic DNA from biological materials. Over the past 10 years or so, clever techniques have been developed for separating the desired DNA component from unwanted RNA, proteins, cellular debris, and chromosomal DNA (in the case of plasmid preps). Most traditional methods of DNA isolation are time consuming, yet they deliver a pure product suitable for virtually any downstream application. However, more and more labs are using DNA purification kits for their speed and convenience.
