Bitesize Bio has been talking about SDS-PAGE lately with a primer on how it works and tips on how to make it work better, but this time Nick discusses how they go wrong. He points to a guide and photo gallery that Rice University's David Caprette has pulled together, called the SDS-PAGE Hall of Shame. "By clicking on the picture that looks most like your poor, messed up gel you will be given a pearl of wisdom that suggests what you might have done wrong so you can remedy it in the future," Nick writes.
