This DNA sample is then loaded into an agarose gel using a micropipette and exposed to an electric current. The DNA size marker is a commercial 1 kBp ladder. Electrophoretograms are evaluated visual-ly for the presence of quantitatively or qualitatively abnor- mal protein bands. However, the high cost of specialized equipment and chemicals often hinder such an experiment from being carried by high school students. Using an electric field, molecules (such as DNA) can be made to move through a gel made of agarose or polyacrylamide.The electric field consists of a negative charge at one end which pushes the molecules through the gel, and a positive charge at the other end that pulls the molecules through the gel. Still the only concise practical guide to laboratory experiments in proteomics, this new edition now also covers DIGE technology and liquid-chromatography, while the troubleshooting section has been considerably extended. 0000002221 00000 n From the earliest days of electrophoresis it has been axiomatic that molecules carrying an electrical charge will .
