Promega is part of a new public-private partnership among Wisconsin industry leaders to increase the state’s laboratory testing capacity for COVID-19. I am pleased to represent Promega in this effort. The valuable insight we at Promega are gaining every day through our participation in this innovative partnership not only benefits Wisconsin labs, it also provides unique understandings about how we can best meet the testing needs of our customers around the world.
The new partnership includes laboratory support from Exact Sciences, Marshfield Clinic Health System, UW Health, as well as Promega. These organizations, along with the Wisconsin Clinical Lab Network, are sharing knowledge, resources, and technology to bolster Wisconsin’s testing capacity. Our goal is to help labs find the quickest approach to the most tests with their validated methods.
Laboratories can be crowded places. We are used to working around other people, tossing ideas back and forth. Dark rooms, cold rooms and large equipment spaces are often shared by several labs. Some labs have shut down completely in response to the COVID-19 pandemic; others, especially those labs doing research around coronavirus biology, testing and detection and drug development are running continually. For those labs, maintaining the recommended 6-foot (2m) distance to help stem the coronavirus pandemic isn’t easy.
At Promega our operations, quality assurance, applications and research and development labs are up and running—focused on providing as much support as possible to our partners who are studying, diagnosing and developing treatments for COVID-19. At the same time, we are maximizing the safety of our employees. Here are a few ways we have found to maintain critical distances in our laboratory that might help your lab group stay productive and safe too.
In December 2019, a new disease emerged from a seafood
market in Wuhan, China. People who were infected began experiencing fever, dry
cough, muscle aches and shortness of breath. The disease swept through China
like wildfire and quickly spread overseas to almost every continent. We now
know the virus that caused this disease, SARS-CoV-2, is a member of the severe
acute respiratory syndrome coronavirus, and the disease itself was officially
named COVID-19. According to the Johns Hopkins University Coronavirus Resource Center,
there are 877,422 confirmed cases of COVID-19 worldwide, and 43,537 total
deaths at the publication of this blog. Those numbers are only expected to
increase over the next few weeks.
In this moment of crisis, scientists all around the world are desperately trying to find ways to treat and prevent the disease. One strategy for preventing the spread of the virus is to block its entry into human cells. But first we need to understand how SARS-CoV-2 enters human cells. A research group at the German Primate Center led by Dr. Stefan Pohlmann provides some answers in a recent publication in Cell.
Many research labs around the world have temporarily closed their doors in response to the COVID-19 pandemic, while others are experiencing unprecedented need for reagents to perform viral testing. This urgency has led many scientists to make new connections and build creative, collaborative solutions.
“In labs that are still open for testing or other purposes, there’s certainly heightened anxiety,” says Tony Vanden Bush, Client Support Specialist. “I feel that right now, I need to help them deal with that stress however possible.”
Last week, Tony was contacted by a lab at the University of Minnesota that was preparing to serve as a secondary COVID-19 testing facility for a nearby hospital lab. The two labs needed to process up to 6,000 samples per day, and the university lab was far short of that capacity.

A Trip Down Memory Lane
Back in the day when we all walked two miles uphill in the snow to get to our laboratories, RNA and DNA extraction was a home-brew experience. You made your own buffers, prepped your own columns and spent hours lysing cells, centrifuging samples, and collecting that fluorescing, ethidium bromide-stained band of RNA in the dark room from a tube suspended over a UV box. Just like master beer brewers tweak their protocols to produce better brews, you could tweak your methodology and become a “master isolater” of RNA. You might get mostly consistent results, but there was no guarantee that your protocol would work as well in the hands of a novice.
Enter the biotechnology companies with RNA and DNA isolation kits—kits and columns manufactured under highly controlled conditions delivering higher quality and reproducibility than your home-brew method. These systems have enabled us to design ever more sensitive downstream assays–assays that rely on high-quality input DNA and RNA, like RT-qPCR assays that can detect the presence of a specific RNA molecule on a swab containing only a few hundred cells. With these assays, contaminants from a home-brew isolation could result in false positives or false negatives or simply confused results. Reagents manufactured with pre-approved standard protocols in a highly controlled environment are critical for ultra sensitive tests and assays like the ones used to detect SARS-CoV-2 (the virus that causes COVID-19).
The Science of Manufacturing Tools for Scientists
There are several criteria that must be met if you are
producing systems that will be sent to different laboratories, used by
different people with variable skill sets, yet yield results that can be
compared from lab to lab.
As scientists, we often find ourselves fielding questions about events in the news that may or may not be related to our area of expertise. Especially during the ongoing pandemic, it can often be difficult to share accurate information without either sparking panic or understating the severity. Nonetheless, we want to support our friends and family in times of uncertainty, and one way to do that is by sharing accurate information about scientific topics.
We’ve gathered answers to a few frequently asked questions
about the COVID-19 pandemic that we’ve received from family members. Have
question we missed? Submit it in the comments and we’ll get back to you.
Depending on your viewpoint, source of information and tolerance for risk, this can be a frightening time for persons all over the planet. The level of disruption to daily life that we’re all experiencing due to COVID-19 is unprecedented.
We are all either not working, working from home and away from our normal offices, or in some cases working many more hours to cover for sick coworkers and caring for SARS-CoV-2-infected persons.
But there is good news if you find that information is power. We hope that some information about the testing being used in the US for this novel coronavirus might be fuel for you, empowering in terms of information.
What is the Name of the Virus, and the Disease? Since this is a global pandemic, the World Health Organization was instrumental in naming the virus and disease. From this web page: the disease is called COVID-19.
The coronavirus responsible for this disease is SARS-CoV-2.
