When creating a PCR protocol, users normally concentrate on the template DNA, reaction mix (buffer, dNTPs, taq polymerase), primers, probes, and the thermocycler, which is the main instrument used to ...

The CDC in July announced its intent to withdraw an emergency use request for a protocol for PCR testing for COVID-19. The withdrawal would become effective Dec. 31, 2021. But that was because of the ...

In a recent study posted to the medRxiv* preprint server, researchers examined sample collection practices, epidemiological characteristics, and cycle threshold (Ct) values for polymerase chain ...

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 polymerase chain reaction (qPCR) is a molecular technique that has reshaped the landscape of biological research and medicine due to its high sensitivity and specificity. qPCR, also known ...

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 ...

Every American traveling abroad needs to take an antigen test to return to the United States. But the start of the trip is often even more cumbersome, as many other countries (nearly every one I have ...
