Abstract
A fluorescent dyed polymer sheet receives excitation energy from ultraviolet wavelengths from 200 nanometers to 370 nanometers and converts to visible light wavelengths. This conversion allows for use of existing ultraviolet light sources to produce visible light for visualizing, photographing, documenting and analyzing electrophoresis gels produced with visible stains. An ultraviolet transilluminator is designed to fluoresce Ethidium bromide stained gels when exposed to ultraviolet light. This process allows visualization of the DNA and RNA bands providing images that can be photographed with black and white photographic cameras or video cameras. By placing the proper fluorescent dyed polymer on the surface of the ultraviolet transilluminator the polymer sheet receives excitation energy from the ultraviolet bandwidth and converts it to visible light wavelength emissions.
