Loading Samples And Running An Agarose Gel For Electrophoresis Gel Carefully load your samples into the additional wells of the gel. run the gel at 80 150 v until the dye line is approximately 75 80% of the way down the gel. a typical run time is about 1 1.5 hours, depending on the gel concentration and voltage. note: black is negative, red is positive. Buffer and staining options for agarose gel electrophoresis "one size fits all" protocol. use 1% agarose gel made in tbe (0.5x). add 1μl of thiazole orange stock per 10ml of gel while gel is molten (after cooling to pouring temperature ~50 c). use tbe (0.5x) as the running buffer. run at 150 180v (small tanks) or 200 250v (large tanks).
Loading Samples And Running An Agarose Gel For Electrophoresis Gel Step 1:set the agarose gel in the electrophoresis tank in the right orientation. remove the tape from both sides of the casting tray (if you have used them for sealing the tray’s both open end). place the gel with a casting tray in the electrophoresis tank in the right orientation. since dna moves from negative to positive electrodes, the. The most common gel running buffers are tae (40 mm tris acetate, 1 mm edta) and tbe (45 mm tris borate, 1 mm edta). sample preparation and loading . samples are prepared for electrophoresis by mixing them with loading dyes. gel loading dye is typically made at 6x concentration (0.25% bromphenol blue, 0.25% xylene cyanol, 30% glycerol). Allow the agarose to set at room temperature. remove the comb and place the gel in the gel box. alternatively, the gel can also be wrapped in plastic wrap and stored at 4 °c until use (fig. 1). 2. setting up of gel apparatus and separation of dna fragments. add loading dye to the dna samples to be separated (fig. 2). This protocol uses a standard electrophoresis system. the agarose gel will be made by adding agarose powder (or tablets) to running buffer, boiling the mixture, then letting it cool into a gelatin like slab. the agarose gel is run in a standard electrophoresis system, then visualized with a transilluminator.

Carefully load your samples into the additional wells of the gel. gel loaded with samples 13 run the gel at 80 150 v until the dy e line is approximately 75 80% of the wa y down the gel. a typical run time is about 01:00:00 01:30:00 , depending on the gel concentration and voltage. note note: black is negativ e, red is positiv e. Part 1: running your gel. add 2.5 µl loading dye to m13ko7 samples from last time. loading dye contains xylene cyanol as a tracking dye to follow the progress of the electrophoresis (so you don’t run the smallest fragments off the end of your gel!) as well as glycerol to help the samples sink into the well.
