Digital PCR, or dPCR, is a molecular biology technique that detects and quantifies nucleic acid targets. By partitioning a sample into many individual reactions, scientists can measure whether a ...

Polymerase chain reaction (PCR) is a fundamental molecular biology tool that scientists use to amplify and analyze genetic material, such as DNA and RNA. PCR involves the enzymatic amplification of ...

A polymerase chain reaction (PCR) test detects genetic material from a pathogen or abnormal cell sample. Ways of collecting samples include a nasal swab, a saliva swab, or taking a sample of blood.

With laboratory methods and diagnostics advancing apace, Francesca Lake considers whether PCR is likely to retain its crown as an essential lab method, or whether it could be replaced and consigned to ...
