A simple method for recording thin-layer acrylamide gel electropherograms.

Thin-layer acrylamide gel electrophoretic technique, based on the method described by Nandi and Lewis,' has been used in our laboratory for the electrophoresis of blood and malaria parasite enzymes. It was found that preservation of the enzyme electropherograms in acid solution is cumbersome, space-occupying, and unstable. Alternative methods for permanent recording of the electropherograms are direct scanning of the gels in a densitometer and photographic techniques. These techniques require extra equipment and skill. In this paper we describe a simple procedure for recording electropherograms of enzyme patterns in their original size and colour.
