Gel electrophoresis is the standard laboratory procedure for separating DNA by size for visualization and purification. In this video, we’ll show you how to prepare an agarose gel using powdered agarose and buffer. Then we’ll show you how to load your samples into the gel and perform electrophoresis to successfully separate your DNA bands. We’ll also give you some tips and tricks to get great looking gels every time!
