If you’ve ever run a DNA or RNA gel at high voltage and cooked/overheated your gel, this post is for you! Scroll to the bottom for the main conclusions of this paper by Sanderson et al which changed the buffer and agarose gel composition to minimize heating. For all my fellow DNA and RNA gel marathon runners: if you want nucleic acid gels to run faster, consider removing EDTA from your buffer! Cover art is the gel from my experiment.
