Buckling Down to Scale Up: Providing Support Through the Pandemic

The past year has been a challenge. Amidst the pandemic, we’re thankful for the tireless work of our dedicated employees. With their support, we have continuously stayed engaged and prepared during all stages of the COVID-19 pandemic so that we can serve our customers at the highest levels.

How We Got Here

The persistent work by our teams has made a great impact on the support we can provide for scientists and our community during the pandemic. From scaling up manufacturing to investing in new automation, every effort has helped.

Promega has a long history of manufacturing reagents, assays, and benchtop instruments for both researching and testing viruses. When the pandemic began in 2020, we responded quickly and efficiently to unprecedented demands. In the past year, we experienced an approximately 10-fold increase in demand for finished catalog and custom products for COVID-19 testing. In response to these demands, we increased production lines. One year ago, we ran one shift five days per week. Currently, we run three shifts seven days per week. This change has allowed 50 different Promega products to support SARS-CoV-2 testing globally in hospitals, clinical diagnostic laboratories, and molecular diagnostic manufacturers. Additionally, our clinical diagnostics materials make up about 2/3 of COVID-19 PCR tests on the global market today. Since January 2020, Promega has supplied enough reagents to enable testing an estimated 700 million samples for SARS-CoV-2 worldwide.

Developments and Advances

Promega products are used in viral and vaccine research. This year, our technologies have been leveraged for virtually every step of pandemic response from understanding SARS-CoV-2 to testing to research studies looking at vaccine response.

Who Got Us Here

We are extremely grateful for our employees. In the past year, we hired over 100 people and still have positions open today. While welcoming newcomers, this challenging year also reinforced the importance of our collaborative culture. Relationships at Promega have been built over multiple years. The long history of our teams allows us to stay coordinated while prioritizing product distribution to customers across the globe. It also leads to effective communication with colleagues and vendors. Those leading our manufacturing operations team, for example, have an average tenure of 15 years. Their history in collaborating through challenging situations helps them quickly focus where needed most.

Our 600 on-site employees support product manufacturing, quality, and R&D. They do it all while remaining COVID-conscious by social distancing, wearing masks, working split shifts, and restricting movement between buildings. While we continue to practice physical safety precautions, we also prioritize our employees’ mental health and wellness. Promega provides a variety of wellness resources including phone and video mental health sessions, virtual fitness and nutrition classes, and stress and anxiety tools.

What’s to Come

While we acknowledge that the COVID-19 is not over, we are proud of the support we have been able to provide to customers working both on pandemic research and critical research not related to COVID-19. Our policies of long-term planning and investing in the future has allowed us to respond quickly and creatively and learn from the experience.

RT-qPCR and qPCR Assays—Detecting Viruses and Beyond

We have all been hearing a lot about RT-PCR, rRT-PCR and RT-qPCR lately, and for good reason. Real-Time Reverse Transcriptase Polymerase Chain Reaction (rRT-PCR) is the technique used in by the Center for Disease Control (CDC) to test for COVID-19. Real-time RT-PCR, or quantitative RT-PCR (RT-qPCR)*, is a specialized PCR technique that visualizes the amplification of the target sequence as it happens (in real-time) and allows you to measure the amount of starting target material in your reaction. You can read more about the basics of this technique, and watch a webinar here. For more about RT-PCR for COVID-19 testing, read this blog.

Both qPCR and RT-qPCR are powerful tools for scientists to have at their disposal. These fundamental techniques are used to study biological processes in a wide range of areas. Over the decades, Promega has supported researchers with RT-qPCR and qPCR reagents and systems to study everything from diseases like COVID-19 and cancer to viruses in elephants and the circadian rhythm of krill.

Researching the Researchers: Alberto Biscontin

2019 Real-Time PCR Grant

The three 2019 Real-Time PCR Grant Winners have been hard at work in the six months since winning their grants. Each winner was eligible to receive up to $10,000 in free PCR reagents as well as the opportunity to collaborate with our knowledgeable technical service and training teams.

One of the 2019 winners, Alberto Biscontin (University of Padova, Italy), performs research in the fields of Neurogenetics and Chronobiology. He is looking to shed greater light on the circadian rhythms of the Antarctic krill. Alberto published his most recent analysis in Nature and GoTaq® qPCR Master Mix helped him validate expression of genes for his study.

His qPCR data showed support for internal mechanisms that not only support daily living but also clarified the overwintering process of the krill. Now that Alberto has sized up some zooplankton, we asked him to share a little more about himself and his research:

Q: How long have you been a researcher?
A: I have been a researcher since 2012.

Q: How did you decide to research Antarctic krill?
A: In 2013, I had the opportunity to join the international Antarctic research program PolarTime. [It] brought together eight research groups with different scientific expertise to study seasonal and daily rhythms in the Antarctic krill Euphausia superba.

Q: When you are not busy at the bench, what do you like to do?
A: Traveling. I love strolling through open-air markets.

Q: Are there any tips or tricks you have learned that make your job easier?
A: You can easily switch from a classic RT-PCR protocol to a cheaper and faster One-step protocol using the same primers and temperatures.

Q: What comes next?
A: I would like to characterize the clock machinery of other polar organisms to understand whether high latitude clocks have developed similar strategies to cope with [the] polar environment. Moreover, a better understanding of marine circadian clocks could help to shed light on the evolution of the animal circadian machinery.

You can find Alberto’s most recent publication in Nature Scientific Reports. The 2020 Real-Time PCR Grant will be coming soon. For more information on the 2019 winners and information on the 2023 Grant, visit the Real-Time Grant web page.

qPCR: The Very Basics

Real-Time (or quantitative, qPCR) monitors PCR amplification as it happens and allows you to measure starting material in your reaction.
qPCR monitors amplification in real and allows you to measure starting material.

For those of us well versed in traditional, end-point PCR, wrapping our minds and methods around real-time or quantitative (qPCR) can be challenging. Here at Promega Connections, we are beginning a series of blogs designed to explain how qPCR works, things to consider when setting up and performing qPCR experiments, and what to look for in your results.

First, to get our bearings, let’s contrast traditional end-point PCR with qPCR.

End-Point PCRqPCR
Visualizes by agarose gel the amplified product AFTER it is produced (the end-point)Visualizes amplification as it happens (in real time) via a detection instrument
Does not precisely measure the starting DNA or RNAMeasures how many copies of DNA or RNA you started with (quantitative = qPCR)
Less expensive; no special instruments requiredMore expensive; requires special instrumentation
Basic molecular biology techniqueRequires slightly more technical prowess

Quantitative PCR (qPCR) can be used to answer the same experimental questions as traditional end-point PCR: Detecting polymorphisms in DNA, amplifying low-abundance sequences for cloning or analysis, pathogen detection and others. However, the ability to observe amplification in real-time and detect the number of copies in the starting material can quantitate gene expression, measure DNA damage, and quantitate viral load in a sample and other applications.

Anytime that you are performing a reaction where something is copied over and over in an exponential fashion, contaminants are just as likely to be copied as the desired input. Quantitative PCR is subject to the same contamination concerns as end-point PCR, but those concerns are magnified because the technique is so sensitive. Avoiding contamination is paramount for generating qPCR results that you can trust.

  1. Use aerosol-resistant pipette tips, and have designated pipettors and tips for pre- and post-amplification steps.
  2. Wear gloves and change them frequently.
  3. Have designated areas for pre- and post-amplification work.
  4. Use reaction “master mixes” to minimize variability. A master mix is a ready-to-use mixture of your reaction components (excluding primers and sample) that you create for multiple reactions. Because you are pipetting larger volumes to make the reaction master mix, and all of your reactions are getting their components from the same master mix, you are reducing variability from reaction to reaction.
  5. Dispense your primers into aliquots to minimize freeze-thaw cycles and the opportunity to introduce contaminants into a primer stock.

These are very basic tips that are common to both end-point and qPCR, but if you get these right, you are off to a good start no matter what your experimental goals are.

If you are looking for more information regarding qPCR, watch this supplementary video below.

Do you want to build a snowman? Developing and optimizing a qPCR assay to detect ice-nucleating activity

Snowflakes---MA-400x600

Over the last few months we have published several blogs about qPCR—from basic pointers on avoiding contamination in these sensitive reactions to a collection of tips for successful qPCR. Today we look in depth at a paper that describes the design and and optimization of a qPCR assay, and in keeping with the season of winter in the Northern hemisphere, it is only fitting that the assay tests for the abundance and identity of ice-nucleating bacteria.

Ice-nucleating bacteria are gram-negative bacteria that occur in the environment and are able to “catalyze” the formation ice crystals at warmer temperatures because of the expression of specific, ice-nucleating proteins on their outer membrane. Ice-nucleating bacteria are found in abundance on crop plants, especially grains, and are estimated to cause one-billion dollars in crop damage from frost in the United States alone.

In addition to their abundance on crop plants, ice-nucleating bacteria are also found on natural vegetation and have been isolated from soil, snow, hail, cloud water, in the air above crops under dry conditions and during rain fall. They have even been isolated from soil, seedlings and snow in remote locations in Antarctica. For the bacteria, ice nucleation may be a method to promote dissemination through rain and snow.

Although ice-nucleating bacteria have been isolated from clouds, ice and rain, little is known about their true contribution to precipitation or other events such as glaciation. Are such bacteria the only source of warm-temperature (above temperatures at which ice crystals form without a catalyst) ice nucleation? Can they trigger precipitation directly? What are the factors that trigger their release from vegetation into the atmosphere? Can we determine their abundance and variety in the environment?

Methods for Quantitating Your Nucleic Acid Sample

Nucleic acid quanitation webinar

For most molecular biology applications, knowing the amount of nucleic acid present in your purified sample is important. However, one quantitation method might serve better than another, depending on your situation, or you may need to weigh the benefits of a second method to assess the information from the first. Our webinar “To NanoDrop® or Not to NanoDrop®: Choosing the Most Appropriate Method for Nucleic Acid Quantitation” given by Doug Wieczorek, one of our Applications Scientists, discussed three methods for quantitating nucleic acid and outlined their strengths and weaknesses.
