International ClassG01N 027/26Foreign Application Priority Data1985-05-29 GBAbstractLight from the pattern of spots of bands resulting from electrophoresis is detected by a two-dimensional charge coupled device, visualization of the spots or band being achieved by irradiating the gel with a U/V source to stimulate fluorescent markers preferably applied before running of the gel. The charge coupled device is cooled to suppress thermal dark current and, more particularly, to improve sensitivity and dynamic range.Other References
