Tm analysis of real-time PCR with SYBR Green as fluorescent dye. Tm analysis allows the differentiation of specific PCR product (amplicon) from non-specific amplification products, such as primer-dimers. Samples: 1 to 7, patient samples (stool); 8, negative control (water); 9, positive control (NoV positive stool). Amplified products from NoV template RNA can be reliably distinguished from non-specific products by different melting points. The melting temperature for the positive samples was 79.0 +/- 0.5°C. Non-specific products melt at lower temperatures.
