Webpulsed field gel electrophoresis (PFGE) resolution. It is the length of time the electrical field is pulsed in a single direction. For example, a 60 sec switch time means that the electrical field will be pulsed in one direction for 60 sec and then switched to the other direction for 60 sec. The switch time is generally shorter for samples with ... WebDNA by pulsed-field gel electrophoresis (PFGE), which is considered to be the method of choice (26).

WebDec 1, 2008 · Pulsed field gel electrophoresis (PFGE) is a technique for the fractionation of high-molecular-weight DNA ranging from 10 kb to 10 Mb by electrophoresis in agarose gel with an electric field that ... WebPulse-Field Gel Electrophoresis (PFGE) PFGE allows investigators to separate much larger pieces of DNA than conventional agarose gel electrophoresis. In conventional gels, the current is applied in a single direction (from top to bottom). But in PFGE, the direction of the current is altered at a regular interval as shown in the animated gif below.
