Remove precast gel from bag, rinse with water.

Wash out wells a total of three times with 1X running buffer using a pasteur pipette. This buffer is provided as a 20X concentrated solution which has to be diluted with de-ionised water. MOPS buffer turns yellow as it degrades (oxidizes).

The following are recipes for a number of common biological buffers taken from Ruzin, 1999 Plant Microtechnique and Microscopy.When choosing one for a particular application select a buffer based on its pH optimum and biological properties rather than its historical use. It will turn yellow with age, and on long exposure to light, and, apparently, when autoclaved. Today I made 10X MOPS buffer for running RNA gels. Peel off tape on back of gel and remove comb.
