Detection of p53 Gene in Breast Cancer by Denaturing Gradient Gel Electrophoresis and the DCode™ System
22 Oct 2013Denaturing gradient gel electrophoresis (DGGE) is one of the most consistently used mutation scanning methods. It has evolved enormously over the last decade to be widely used, particularly in gene diagnostic laboratories. This application note demonstrated the use of DGGE to screen p53 mutations in breast cancer.

ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.
