If the voltage is too high, band streaking, especially for DNA ≥12 kb - 15 kb, may result.

  • How current, voltage, and power settings affect SDS-PAGE

    2021-6-29 · The larger the gel, the higher the voltage. Once your proteins are on the resolving gel, you can increase the voltage. One rule of thumb is to set your voltage at about 5-15 V per centimeter of gel. Small gels will run closer to 100V, while large gels may approach 300V. Timing will vary for this step, ranging from 45 min to 2 hours.

    2021-6-30 · How would you know how much protein to load on a gel? Calculations. Suppose you’re running a protein gel. You perform a protein assay on your sample, with 20 µl protein sample and 180 µl working solution. You measure a protein concentration of 40 µg/ml in the assay tube. What is the protein concentration in your sample tube (in µg/ml)?

    2007-11-14 · The problem is that the gels seem to run extremely slowly. I'm running a 12% gel right now (SDS-PAGE, 3.5% stacking, 12% sep) and I'm over 1 hour into the run with easily another hour to go, if not longer to go. The sample/dye has just barely made it into the separating gel. I'm running at 100 volts (anything higher and the buffer will be too hot).
