Rapid, high-sensitivity imaging of radiolabeled gels with microchannel plate detectors

A microchannel plate detector has been used to image tritium-labeled protein on one- and two-dimensional electrophoresis gels. The good spatial resolution (70 microns) and high sensitivity (6.0 dpm/mm2) of the imaging system allows detection of low levels (femto moles) of labelled proteins. We are currently using the detector for identification of new targets involved in organophosphate neurotoxicity.
