Light Box

Description (Brief)
This UV light box was used in the lab of Stanley Cohen at Stanford University in his research on recombinant DNA. UV light boxes are used to help visualize results from of DNA and RNA analysis through gel electrophoresis. Molecules subjected to gel electrophoresis create a pattern of bands on a gel medium as they move. Scientists can interpret the pattern to obtain the results of the analysis. However, because the bands of molecules are naturally colorless, they must be dyed to be made visible. Dyes that fluoresce under UV radiation are commonly used. This UV light box was used to provide illumination behind the dyed bands, causing them to fluoresce so that they could be photographed and interpreted.
