Real-Time PCR Amplification of Saliva DNA from the saliva ... from saliva samples preserved for over 6 years using Norgen's Swab DNA Preservative. The saliva DNA was isolated using Norgen's ...

a saliva swab, or taking a sample of blood. PCR testing allows researchers to make many copies of a small section of DNA or RNA, in a process that some call “molecular photocopying.” ...

but light is now further facilitating PCR-free methods. Osaka Metropolitan University scientists have developed a light-induced DNA detection technique, using heterogeneous probe particles ...

The team ensured proper sampling using a human DNA-specific RT-PCR reaction. The researchers ... which is not an optimal metric for crusts and dry swab samples. Encouragingly, all controls ...

Researchers have developed a light-induced DNA detection method that enables rapid, PCR-free genetic analysis. Their technique offers ultra-sensitive mutation detection in just five minutes ...
