In this part of the laboratory, you will use gel electrophoresis to separate samples of DNA that have been digested by restriction enzymes. , through a fixed diaphragm—the phenomenon is called electroosmosis. This solution is then cooled to approximately 56°C and the molten gel is poured in a gel tray fitted with a Teflon comb. DNA is driven through the agarose matrix by electric current. Small DNA molecules move through the gel faster than large ones. Once the gel is cool, place it in the electrophoresis apparatus, cover it with 1xTAE (just covering the gel) and then remove the comb. The initial preparation for the lab was conducted on a separate day, as to allow for the gel to harden and settle. length in base pairs) for visualization and purification. In the gel the addition of the transposon to this region causes the 1,800 bar to stay back to where the 2,800 base-pair bar is and makes it look like just one bar on the gel. provide researchers with Òoff-the-shelfÓ convenience and help to make gel electrophoresis an ÒeverydayÓ laboratory procedure.
