    2018-3-5u2002·u2002Polyacrylamide Gel Electrophoresis (PAGE) When electrophoresis is performed in acrylamide or agarose gels, the gel serves as a size-selective sieve during separation. As proteins move through a gel in response to an electric field, the gel's pore structure allows smaller proteins to travel more rapidly than larger proteins (Figure 2.1).

    2018-2-20u2002·u2002Run 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. The DNA is negatively charged and will run towards the positive electrode. Always Run to Red.
