Coli target remains resistant to cleavage, while the probe hybridized to the P. testosteroni rDNA was progressively digested with increasing concentrations of S1 (Fig. 4). In this experiment, probe specificity was attained at 40 units of S1 per reaction without obvious loss of probe in the positive control. M. Schmidt et al. 44 Sl ANALYSIS E. 4 4 Ps. 4. Autoradiogram of an Sl nuclease protection assay with PCR-generated rDNA from E. coli and P. testosteroni. The isotopically labeled rRNA probe was transcribed from the E.

The intent of this work is to introduce the use of probes complementary to ribosomal RNA (rRNA) as a universal tool for identification of bacteria, fungi, or protozoa and their application in diagnosis and epidemiology of infectious diseases as well as in industrial and environmental microbiology. Background The properties of an "ideal" probe, such as absolute specificity, maximum sensitivity, excellent availability, which lends itself to the development of a rapid, accurate, easy to use and standardize, cost-effective test, are all combined in rRNA-based probes.

Most solution hybridization procedures involve a separation of bound and unbound probe, by capturing DNA/rRNA heteroduplexes by either binding to hydroxylapatite or reaction with antibodies directed against DNA/rRNA hybrids (Kohne et al. 1984; Boguslawski et al. 1986; Rashtchian et al. 1987; Yehle et al. 1987; Coutlee et al. 1989; Thompson 1989). Heterogeneous assays which require separation steps are difficult to perform and time-consuming. To further simplify the tests homogeneous assays have been developed in which hybridization and detection of hybrid molecules are performed in the same vial without any separation step.
