We report here on a traditional paper electrophoresis separation of amino acids. a state-of-the-art aearose eel electrophoresis separation ~ ~ ' D Nfragments, A a 2 on tG design of an electro~horesistank which combines outstandine safetv features with the ahility to conduct both paper and gel eleltrophoresis experiments. A drawing of the electrophoresis tank is shown in Figure 1. Like a commercially available tank,2 our tank has a rotatine cover; since the two electrical connections are made throug6 holes in the cover, electric current cannot be applied to the tank unless the cover is closed. As an additional safety feature, banana jacks are used on the electrical leads, and mate with banana plugs in the tank. Although banana jacks can he purchased, we found that the commercially available jacks are not lone enoueh to Dass throueh the holes in the cover and reach
