摘要：

Tritium-labelled cell cultures used in studies of lymphocyte proliferation at the Clinical Research Centre are blotted in arrays of 10 x 6 spots spaced at 6 mm. An imaging detector based on the differential induction signals produced at a central amplifying electrode has been developed for the imaging and assay of these blots. A spatial resolution approximately 2.5 mm FWHM attained over the aperture of 60 mm x 36 mm enables the individual spots to be reliably counted. Data is captured in a PC/AT at rates which permit an assay to be completed in typically 30-60 min. The simplicity of both the detector and the readout electronics leads to a low cost system. Images and assay results are presented.
