Detection of K-ras Point Mutations in the Pancreas by Constant Denaturing Gel Electrophoresis using the DCode™ System

28 May 2013

Mutations of K-ras were thought to be quite rare in pancreases free of ductal adenocarcinoma. In this application note constant denaturing gel electrophoresis detected mutations in 16 samples from normal pancreases. This finding raises the question of which role K-ras mutations play in the series of genetic alterations leading to ductal adenocarcinoma of the pancreas.

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.
