Witryna1 lut 2005 · Real-time PCR and nucleic acid sequence–based amplification (NASBA) are promising methods of nucleic acid detection. NASBA is a new technique that involves amplification and detection of mRNA. It differs from PCR in several ways: it is an isothermal process, it uses RNA polymerase, and it amplifies mRNA and not DNA . … WitrynaOriginally envisaged as an improved diagnostic method for detection of RNA viruses, NASBA™ has been developed into a technology with much wider application. NASBA™ technology depends on selective primer-template recognition to drive a cyclic, exponential amplification of the target sequence ( 1 ). Notably, NASBA™ operates …

WitrynaThe two most common methods include heat denaturation at 95°C and alkaline DNA denaturation. Heat denaturation carries the risk of DNA breakage, whereas alkaline denaturation may be incomplete and inconvenient. Intact but well-separated stretches of starting DNA ensure lower bias and higher yields.
