With the technique called polymerase chain reaction (PCR), scientists can make multiple copies of a specific genetic sequence within DNA. PCR is a powerful tool for researchers because it allows for ...

Individual components, including the template, primers, polymerase, dNTP levels, and cycling conditions, can impact the overall PCR reaction. Explore how these ...

Designing reproducible PCR assays involves optimizing multiple moving targets, from standardizing each component in sometimes minute reaction volumes to planning ahead to ensure long-term and secure ...

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.

Quantitative PCR (qPCR) instruments that operate in real-time need high sensitivity and the most favorable signal-to-noise ratio possible. The bandwidth of excitation, center wavelength (CWL) and ...
