WebSep 1, 2016 · Pulsed-field Gels. If you’re working with large DNA—anything greater than 10 kb—then you’ll need a pulsed-field gel. 1 Long pieces of DNA get clogged up going through gels, so the pulsed-field approach gets around this by applying electrical fields in different directions, alternating the voltage to prevent the fragments from getting ...

WebMar 5, 2024 · DNA fragments resolved on polyacrylamide gels can also be visualized by the method of UV shadowing . In this method the gel is placed on top of a fluorescent material, usually a flourescent TLC silica plate. The gel is then illuminated by a UV light source. DNA bands in the gel will block transmittance of the UV light to the substrate. WebWe have developed an application to calculate double-stranded DNA fragment size on an agarose gel. This application is named GEL and is implemented for two different platform: MS-DOS and Macintosh. Both implementations allow entry of the relative migration distance of a DNA fragment of an agarose gel containing up to 20 different wells and up ...
