Polymerase chain reaction (PCR) is a revolutionary laboratory technique that enables the replication of a specific DNA sequence. Using PCR, millions of copies of a target DNA can be easily synthesized within a short period of time.
The COVID-19 pandemic has highlighted the need for rapid and accurate nucleic acid detection at the point of care.
Researchers from the University of Basel have developed a sensitive testing system that allows the rapid and reliable detection of resistance in bacteria.
A recent paper explored the possibility of using serologic testing as an adjunct diagnostic method in the diagnosis of SARS-CoV-2 infection.
A paper published on medRxiv describes a repurposed type III CRISPR-Cas system that can detect the virus from nasopharyngeal swabs in less than an hour.
Researchers at the University of Colorado Boulder and the University of Colorado Anschutz Medical Campus have developed a new way to diagnose diseases of the blood like sickle cell disease with sensitivity and precision and in only one minute.
In May, a fishing vessel exited a port and returned with the first-ever proof that neutralizing antibodies offer protection from being re-infected by SARS-CoV-2.
Rare genetic mutations occurring in cells cannot be detected by existing sequencing techniques because these methods do not have the required sensitivity.
Researchers have revealed a connection between methylation of genes implicated in heme synthesis and carcinogenesis and high blood lead levels in children, signifying a previously unfamiliar mechanism for lead poisoning.
A rapid laboratory test, the eosinophil count, readily obtained from a routine complete blood cell count (CBC) can aid in the early recognition of COVID-19 in patients, as well as provide prognostic information, according to new research in The Journal of the American Osteopathic Association.
Both symptomatic and asymptomatic COVID-19 patients have the capability of contaminating their surroundings, according to a new study published in mSphere.
MicroRNAs, are attracting interest relating to human diseases because variations in the expression of miRNAs are often associated with abnormal functions.
Researchers have developed a technique to ensure that DNA fingerprinting continues to be secure against malicious attacks or mistakes in the field.
With the number of COVID-19 cases reducing in the United States and elsewhere, public health officials are attempting to understand the proportion of people who have been infected by coronavirus.
Professor Ruiting Lan speaks to AZoLifeSciences about his research into tracking salmonella poisoning and outbreaks.
