A new approach to amplifying DNA - Phys.org

WebThe branched DNA (bDNA) assay provides a unique and powerful tool for reliable quantification of nucleic acid molecules. Fundamentally different from target amplification methods such as PCR, the bDNA assay directly measures nucleic acid molecules at physiological levels by boosting the reporter signal, rather than replicating target … WebAmplification enables detection of the target even when sample size is small or when there are very few strands of DNA or RNA present. There are three types of amplification: The assay makes more copies of target nucleic acid before detection. Polymerase chain reaction (PCR) is the typical target amplification method.
