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

PCR is a technique used to amplify target DNA in a sample. It’s a well-known method that has undergone numerous modifications to enhance its capabilities. This year, it’s turning 40 years old. PCR has ...

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 ...

Polymerase chain reaction (PCR) and rapid (antigen) tests for COVID-19 both involve taking a swab. Results for a PCR test take longer, as it needs to go to a laboratory. It is more costly but tends to ...

With Omicron surging in the United States, many people are taking COVID-19 tests to see whether they test positive. Most people will take either a rapid antigen or PCR test. Though the PCR test is ...
