We started ethidium DNA agarose gel electrophoresis when our ultracentrifuge broke down and we needed an alternative method to check the quality of our mitochondrial DNA preparations. Agarose proved convenient for sizing DNA; ethidium in gel and buffer allowed visualization of DNA bands immediately ...
Gel electrophoresis is the tried and true method to analyze and isolate DNA fragments based on size. Following electrophoretic resolution, specific bands can be excised an agarose gel matrix and further processed to purify the DNA. For many workflows, gel electrophoresis is still the best way to...
Historically, pulsed-field gel electrophoresis (PFGE) has been the primary way of DNA fingerprinting STEC to identify and investigate outbreaks. In the wake of the 1992-93 Jack in the Box outbreak, in 1996, the Centers for Disease Control and Prevention (CDC) founded PulseNet, a national labo...

You might be interested to read that molecular biologists capitalize on this property of DNA to isolate DNA fragments of differing sizes. Because DNA is negatively charged, molecular biologists often use agarose gel electrophoresis to separate different sized DNA fragments when DNA samples are subjected...
For this 'bottom-up approach' to proteomics, the first step in the preparation process is purification, for which there are a variety of methods. Gel electrophoresis remains a workhorse favorite, with two-dimensional gel electrophoresis being particularly useful for mass spectroscopy preparation. “...
