Hace 5 días · PCR, o la reacción en cadena de la polimerasa, es una reacción química que los biólogos moleculares utilizan para amplificar (crear copias) fragmentos de ADN. Esta reacción permite que unos pocos fragmentos de ADN se repliquen en millones o miles de millones de copias.
Hace 1 día · Molecular approaches, such as conventional polymerase chain reaction (PCR) and real-time PCR (qPCR), are well-established and considered powerful diagnosis tools (Bienapfl et al., 2011; Haudenshield et al., 2017; Xiong et al., 2019). However, culturing and baiting detection methods are time-consuming and relatively insensitive.
Hace 1 día · Polymerase Chain Reaction (PCR) is a technique developed in 1983 by Kary Mullis, for which he was awarded the Nobel Prize in Chemistry in 1993. PCR allows for the amplification of specific DNA sequences, making it possible to generate millions of copies of a particular DNA segment from a minuscule initial sample.
Hace 5 días · Objective: Universal polymerase chain reaction (PCR) screening for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on hospital admission is an effective approach to preventing coronavirus disease 2019 (COVID-19) outbreaks in medical facilities. However, false-positive test results due to a recent infection are a concern.
Hace 1 día · Polymerase chain reaction (PCR)-based nucleic acid testing has played a crit. role in disease diagnostics, pathogen surveillance, and many more. However, this method requires a long turnaround time, expensive equipment, and trained personnel, limiting its widespread availability and diagnostic capacity.
Hace 2 días · laboratory-confirmed polymerase chain reaction (PCR) in a clinical specimen a positive lateral flow device (LFD) test, where applicable The case definition may differ from the epidemiological definition in the context of an outbreak investigation, for example, a presumed positive case may based on symptoms and epidemiological link to another case.
