Abstract
An imaging screen for detecting and storing information corresponding to the pattern of emission from an electrophoresis gel containing radioactively labelled, dye-tagged or chemiluminescent labelled DNA, RNA, or protein fragments. The imaging screen is coated with an electron trapping material which releasably stores energy from the impingement of the emission from the electrophoresis gel in the form of energy corresponding the pattern and flux of the emission. When subjected to optical energy of a first wavelength, the electron trapping material releases the stored energy in the form of optical energy of a second wavelength corresponding the flux and pattern of the emission from the electrophoresis gel. The released optical energy of a second wavelength is then detected and coverted to electrical signals representative of the flux and pattern of emission from the electrophoresis gel.
