Overview of Digital Electrophoresis Analysis

Abstract

Digital imaging is the method of choice for documentation and analysis of electrophoretic separations of protein and DNA. Digital images of gel electropherograms can be obtained rapidly using CCD-based cameras, and the images can be easily archived and analyzed using image analysis software. This overview defines important key terms and calculations for imaging, explains the capture process, reviews the range of CCD technologies used for image capture, and provides an introduction to the software and methods used for one- and two-dimensional digital image analysis.
