A NOVEL QUANTITATIVE RECEPTOR AUTORADIOGRAPHY AND IN-SITU HYBRIDIZATION HISTOCHEMISTRY TECHNIQUE USING STORAGE PHOSPHOR SCREEN IMAGING

A new technique of image acquisition for quantitative receptor autorad iography and in situ hybridization histochemistry was developed using storage phosphor screen imaging. This method was at least 4-5 times fa ster than conventional film densitometry. Two of the advantages of the phosphor screen method are high sensitivity and wide linear range of response. Other aspects of this method were compared with those of con ventional densitometry. Use of storage phosphor screen imaging will al low greatly increased speed of pharmacological screening procedures th at utilize quantitative autoradiography.
