title: The use of a multiwire camera for the detection of 3H labelled cDNA/mRNA hybrids.
abstract: We have investigated the use of a multiwire camera for the rapid direct quantitation of 3H labelled cDNA/mRNA hybrids. Growth hormone (GH) complementary DNA (cDNA) probes were labelled with either 3H or 32P and used in dot-blot hybridization assays of pituitary cytoplasmic samples. The results were assessed either by counting in the multiwire camera (3H) or by autoradiography and scanning densitometry (32P). Results obtained by both methods were comparable over a similar range of pituitary cytoplasmic dilutions. The use of a multiwire camera may have several advantages over conventional methods for the detection of radioisotopically labelled cDNA/mRNA hybrids and has great potential for use in this field of endocrine research.
