Pulsed field gel electrophoresis — Historical Background Standard gel electrophoresis techniques for separation of DNA molecules provided huge advantages for molecular biology research. However, many limitations existed with the standard protocol in that it was unable to separate… … Wikipedia
pulsed-field gel electrophoresis — ˌ ̷ ̷ ˌ ̷ ̷ noun : gel electrophoresis that is used especially to separate large fragments of DNA and that involves changing the direction of the electric current periodically in order to minimize overlap of the spots due to diffusion … Useful english dictionary
pulsed-field gel electrophoresis — Abbreviation: PFGE A procedure used to separate very large (50 kbp to several Mbp) DNA molecules by alteRNAting the direction of electric current in a pulsed manner across a gel … Glossary of Biotechnology
Gel electrophoresis — apparatus – An agarose gel is placed in this buffer filled box and electrical field is applied via the power supply to the rear. The negative terminal is at the far end (black wire), so DNA migrates toward the camera. Classification… … Wikipedia

pulsed-field electrophoresis — a method of gel electrophoresis used to separate fragments of DNA as long as several million bases by subjecting the gel to an electrical current alternately delivered from two angles in timed intervals, which minimizes diffusion of large… … Medical dictionary
Electrophoresis — is the most well known electrokinetic phenomenon. It was discovered by Reuss in 1809. [Reuss, F.F. Mem.Soc.Imperiale Naturalistes de Moscow , 2, 327 1809] He observed that clay particles dispersed in water migrate under influence of an applied… … Wikipedia
electrophoresis — A ubiquitous molecular biology technique, with many variants, used to resolve complex mixtures of macromolecules into their components. Its principle is to subject samples to an electric field applied across a porous matrix. Molecules will… … Glossary of Biotechnology
Agarose gel electrophoresis — is a method used in biochemistry and molecular biology to separate DNA, or RNA molecules by size. This is achieved by moving negatively charged nucleic acid molecules through an agarose matrix with an electric field (electrophoresis). Shorter… … Wikipedia
