Getting a PhD in Sweatpants: Guest Blog by Dr. Susanna Harris

Posted on by Promega

Today’s blog is guest-written by Susanna Harris, who recently defended her PhD thesis at the University of North Carolina in Chapel Hill.

I just defended my PhD. Nearly six years of blood, sweat, and tears, most of which were cleaned up with Kimwipes while sitting at my desk in a laboratory facing out towards the UNC Chapel Hill football field. Nearly six years of work, all summed up in a handful of slides. Nearly six years of work, explained to my friends, family, and colleagues – a moment I had dreamed of since the fall of 2014.

What I hadn’t dreamed of? That I would be sitting at my small desk in the corner of my room, with no present audience aside from my snoring dogs. That there would be no dinner celebration that carried into a night of fun along Franklin Street. That, unseen by the viewers of my defense, I would be wearing sweatpants as my name changed from Ms. to Dr. Harris.

Why did I wear sweatpants when I could have worn literally anything in my closet? Because I think it’s hilarious. I believe this situation will end and we will walk away with memories and lessons learned from an extremely difficult time in the history of the world. I want to walk away with one more ridiculous story to add to a long list of “What even was that?” tales from grad school.

Working towards a PhD is hard at any time; let’s not pretend this pandemic isn’t making things even worse. I was fortunate in many ways that my advisor had already moved our laboratory to a new state in 2019, allowing me to adjust to meeting through webcams and working from home before the pandemic changed the lives of all North Carolinians. This has given me a unique perspective to tease out which problems come from distance working and which are the result of Safer-At-Home orders. Based on my experiences, here are a few tips, tricks, and words of warning.

Earth Day 2020: Celebrating Nature During A Pandemic

Posted on by Jordan Villanueva

Since Wisconsin issued a Safer at Home order on March 25, I have been leaving my home exactly once a week. Every Tuesday morning, I drive to a small town outside of Madison to spend an hour monitoring a nest of bald eagles. I’ve been volunteering for Bald Eagle Nest Watch since the beginning of the year, and three weeks ago I got my first look at two newly hatched eaglets. Over the past few weeks, I’ve found that my time at the eagle nest is a wonderful relief from the stress of the pandemic and the confinement to my home.

I’m not the only person escaping to natural spaces for relief during the widespread lockdowns in response to COVID-19. Parks have been filled with people taking daily walks and enjoying fresh air when there are few places indoors they can safely go. Besides encouraging many people to visit local parks and forests, the COVID-19 pandemic has revealed many complexities of humanity’s relationship with the environment. The severe drop in human activities has resulted in decreased air pollution, as well as fascinating changes in wildlife behavior. However, the pandemic is also an important reminder that the environmental impact of human activity has drastic consequences for global risk of infectious disease. This Earth Day, it’s the perfect time to pause and examine how the COVID-19 pandemic and the natural world are influencing each other for better and for worse.

RT-qPCR and qPCR Assays—Detecting Viruses and Beyond

Posted on by Kelly Grooms

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.

Flexible Automated Purification Solutions For Dealing With Urgent Needs

Posted on by Jordan Villanueva

Implementing a new high-throughput (HT) nucleic acid purification workflow or scaling up an existing workflow presents many unique challenges. To be successful, the chemistry and liquid handler must be perfectly integrated to fit your lab’s specific needs. This involves configuring the instrument deck, optimizing the assay chemistry, and programming the instrument.

When you’re facing a sudden spike in sample throughput demand combined with unprecedented urgency, those challenges can often become overwhelming. Even in times of crisis, Promega scientists are prepared to support labs facing challenges with HT workflows, regardless of your instrumentation platform.

Fighting the COVID-19 Pandemic With Antibody Testing: The Importance of Serological Assays

Posted on by Promega

Today’s blog is written by Ashley G. Anderson, MD, Chief Medical Officer at Promega.

The need for reliable virus detection methods is central to the global response to COVID-19. These test results not only inform health decisions for individual patients, but they also help us build projections of how the virus will spread, which can in turn influence policy decisions.

Following the emergence of COVID-19, PCR-based tests were developed and deployed to detect the virus in patients in hospitals. PCR, or Polymerase Chain Reaction, is a common technique used in labs to amplify large quantities of DNA. The detection tests use swabs placed deep into the back of the nose to detect genetic material carried by SARS-CoV-2, the virus causing COVID-19.

Those tests have been crucial to monitoring infection rates and informing patient treatment, but at this point they have fallen short of providing an overall picture of the pandemic. We know that thousands more cases have likely gone untested due to mild or unnoticed symptoms or lack of access to tests. Since PCR-based methods can only tell us if the virus is active in the patient at the time of sample and offer no information about whether a patient has been infected in the past, we currently have no way to determine how many of these unconfirmed cases exist or which patients have recovered. Serological assays are the one of the most promising tools to address that question.

10 Tips to Maintain Physical Distancing in the Lab

Posted on by Michele Arduengo

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.
