Giving Compass' Take:
• Researchers are developing more reagents to simplify and extend their use for COVID-19 testing so that it can become easier and more productive in the future.
• How help fund research for COVID-19 testing?
• Learn more about coronavirus testing.
The high demand for the reagents used in COVID-19 tests has created some supply issues in the UK (and even more so for developing countries) so the researchers decided to try to make more of the enzymes needed to produce reagents themselves that they could then use in commercially available testing kits.
They not only succeeded in producing more of those crucial and much sought-after enzymes that will make more reagents for testing kits, they may also have found ways that could extend and simplify their use in COVID-19 tests.
They then provided these to laboratories in two UK hospitals, that tested and confirmed that they were effective in creating more COVID-19 testing. They also sent the same materials to the Africa Centres for Disease Control and Prevention (Africa CDC) where the need for reagents is even more pressing.
The research team’s work may also provide opportunities to enhance the current commercial tests, extending the range of temperatures at which they can be used, and maybe even simplifying future production.
“The commercial providers of the reagents and enzymes have themselves found and described eight interesting mutations to their reverse transcriptase, but to our knowledge they had not yet all been combined in the same molecule,” says Mohan K. Balasubramanian a professor in the Warwick Medical School at the University of Warwick.
