    摘要: A method is described for the real-time detection of Salmonella species in foods and on surfaces. Salmonella are enriched in media to increase their cell density prior to analysis. DNA is recovered by lysis in the presence of azide, proteinase K, and detergent. Real-time detection of Salmonella species is performed in a PCR reaction using gene specific primers and a cleavable chimeric fluorescent probe. The method also describes an internal control to confirm the efficiency of nucleic acid amplification and detection. The method is amenable to medium and high throughput analysis.

    摘要: A reversibly modified ‘hot start’ RNAse H enzyme composition is described for the improved CATACLEAVE™ probe detection of nucleic acid sequences in a test sample. A key feature of the enzyme composition is the ability to regulate the catalytic activity of the RNAse H during the course of a reverse transcription-PCR cycle. Thus, RNAse H activity can be initially suppressed to minimize degradation of RNA:DNA primer heteroduplexes prior to reverse transcription. After cDNA synthesis is complete, RNAse H activity is induced to promote the cleavage and fluorescent detection of CATACLEAVE™ probes that anneal to target DNA sequences within the reverse transcriptase-PCR products. The inducible RNAse H enzyme is amenable to high throughput applications requiring one step reverse transcriptase CATACLEAVE™ PCR in a single reaction mix.
