RNA extraction

More than 70 percent of labs surveyed experienced supply chain interruptions, forcing them to validate three or more diagnostic testing methods.

Several labs and at least one company have been working on assays that add samples directly to the PCR reaction and don't require RNA extraction, a time-consuming step.

The partners will launch Zymo's DreamPrep NAP workstation to streamline DNA/RNA extraction for high-complexity testing labs running COVID-19 assays.  

North Dakota-based MedScan Laboratory will collect patient samples and extract RNA for Fulgent's new NGS-based clinical assay for SARS-CoV-2.

The Stanford University spinout claims it can get three times the nucleic acid yield as column- or magnetic bead-based methods, with less damage to the molecules.

The company anticipates launching an in vitro diagnostic version of the 10-gene ThyroidPrint assay in South America and Europe after receiving regulatory clearance by Q2 2021.

The platform is designed to isolate exosomes from blood, then release their extracellular RNA cargo for analysis as biomarkers for diseases including cancer.

Applied BioCode said that it now has access to higher volume laboratories that use the Roche MagNa Pure 96 System for sample extraction.

The startup, which was founded by two Washington University researchers and a Wharton MBA, is looking to take a big bite out of Cologuard's market.
