First Point-of-Care Test for COVID-19 Leveraging CRISPR Technology
Sherlovk Biosciences and binx health announced that the companies have entered a partnership to develop the world’s first point-of-care diagnostic test for COVID-19 leveraging CRISPR technology.
The organizations will combine the binx io diagnostic platform with SHERLOCKTM CRISPR technology to provide rapid results. Their test is designed to deliver results in a single-patient visit across many CLIA-waived settings such as clinics, doctors’ offices, assisted-living centers, pharmacies, and other accessible venues for consumers.
The binx io is a molecular platform with FDA clearance for chlamydia and gonorrhea testing and a proprietary detection method with the ability to detect infectious disease targets from bodily fluids. The platform consists of a desktop-sized instrument and a single-use cartridge with multiplex capacity up to 24 targets. After a patient’s sample is added to the cartridge and loaded into the instrument, the process is fully automated and will produce a “detected” or “not detected” onscreen result.
“We are pleased to partner with Sherlock Biosciences to help bridge a gap in COVID-19 testing—the need for highly accurate point-of-care diagnostic testing in CLIA-waived and near-patient settings,” said Jeff Luber, CEO of binx health. In April, binx health presented an FDA-cleared molecular diagnostic instrument for chlamydia and gonorrhea in both men and women that for the first time delivers same-visit diagnoses.
“Our proprietary platform will now leverage Sherlock’s CRISPR-based assay combined with binx’s eletrochemical detection for rapid viral detection of SARS-CoV-2 without the need for additional instrumentation. This union of technologies is designed to enable physicians, clinicians, and other healthcare workers on the front lines of the global COVID-19 pandemic to make on-the-spot care decisions and to control and prevent further infections,” noted Luber.
Rahul Dhanda, co-founder, president, and CEO of Sherlock Biosciences also stressed the importance of being able to make on-the-spot care decisions. “The response to provide high-volume testing, including Sherlock’s own, has increased access to crucial results during the pandemic. While we have solutions for individuals who can reach hospitals, we still need to make testing accessible in other areas, like pharmacies, to empower individuals to proactively make decisions to improve their health, as well as prevent potential spread to those in their communities,” Dhanda told GEN.
Sherlock agrees with binx health’s strategy of “everywhere care” that depends on highly accurate in-clinic and easy-to-use at-home solutions. Sherlock hopes to serve as part of the solution to addressing the COVID-19 pandemic by making diagnostics available everywhere they are needed.
The current SHERLOCK CRISPR SARS-CoV-2 kit uses the SHERLOCK (Specific High-sensitivity Enzymatic Reporter unLOCKing) method to program a CRISPR molecule to detect the presence of a specific SARS-CoV-2 genetic signature in specimens collected from patients suspected of COVID-19 by their healthcare provider. The SHERLOCK CRISPR SARS-CoV-2 kit is intended for use in CLIA laboratories to assay nasal swabs, nasopharyngeal swabs, oropharyngeal swabs, or bronchoalveolar lavage (BAL) specimens. When the signature is found, the CRISPR enzyme is activated and releases a detectable signal, yielding results in about an hour. The kit is the first CRISPR-based diagnostic test to receive EUA from the FDA for qualitative detection of nucleic acid from SARS-CoV-2.
Back in May, GEN spoke with Dhanda when Sherlock was establishing relationships with suppliers, manufacturers, and partners. Dhanda had expressed their hopes “for the best outcome for public health” and it seems that hope is coming into fruition with this partnership.
Sherlock is also moving forward in developing its INSPECTR at-home testing platform to create an instrument-free, handheld test—similar to that of an at-home pregnancy test—for the rapid detection of the SARS-CoV-2 virus.
The companies plan to launch the test in the second half of 2020.
Ubigene Biosciences is co-founded by biological academics and elites from China, the United States, and France. We are located in Guangzhou Science City, which serves as a global center for high technology and innovation. Ubigene Biosciences has 1000㎡ office areas and laboratories, involving genome editing, cell biology technology, and zebrafish research. We provide products and services for plasmids, viruses, cells, and zebrafish. We aim to provide customers with better gene-editing tools for cell or animal research.
We developed CRISPR-U™ and CRISPR-B™(based on CRISPR/Cas9 technology) which is more efficient than general CRISPR/Cas9 in double-strand breaking, CRISPR-U™ and CRISPR-B™ can greatly improve the efficiency of homologous recombination, easily achieve knockout (KO), point mutation (PM) and knockin (KI) in vitro and in vivo.
