Using Databases to Find Scholarly Sources

Posted on by Promega

Today’s guest blog was written in collaboration with Melissa Martin, a former global marketing intern with Promega. She is a senior at the University of Wisconsin-Madison where she is double majoring in zoology and life sciences communication, with a certificate in environmental studies.

Peer-reviewed papers are considered the most technical and in-depth way to learn about research and scientific advances. As a student or scientist, you will not only want to read scholarly articles to learn about what others are doing in your field but also to expand your knowledge and learn about scientific advances in completely new areas of study. With countless disciplines of science covering wide-ranging topics such as cell biology, physical chemistry or human behavior, it can be overwhelming to do a general search and find articles and journals that will have the topics relevant to your interests.

Posted on by Promega

Today’s guest blog is written by Sophie Mancha, a former global marketing intern with Promega. She is in her 4th year as a PhD candidate in the Biomedical Engineering Department at the University of Wisconsin-Madison, studying pancreatic cancer.

Whether you are applying for a scholarship or trying to land a position in a research lab, there are plenty of decisions to make. Arguably, the most critical consideration is what documents to include to showcase that you are the right person for the job. Specifically, should you be preparing a curriculum vitae (CV) or a resume? What exactly is the difference?

How Can You Improve Protein Digests for Mass Spectrometry Analysis?

Posted on by Promega
Can predigestion with trypisin (ribbon structure shown) improve protein digests for mass spectrometry analysis?
Can pre-digestion with trypsin improve mass spec analysis?

The trypsin protease cleaves proteins on the carboxyterminus of Arginine (Arg) and Lysine (Lys). This cleavage reaction leaves a positive charge on the C-terminus of the resulting peptide, which enhances mass spectrometry analysis (1,2). Because of this advantage, trypsin has become the most commonly used protease for mass spectrometry analysis. Other proteases which cleave differently from trypsin, yielding complementary data are also used in mass spec analysis: these include Asp-N and Glu-C , which cleave acidic residues, and chymotrypsin which cleaves at aromatic residues. The broad spectrum protease, proteinase K is also used for some proteomic analyses. In a recent study, Dau and colleagues investigated whether sequential digestion with trypsin followed by the complementary proteases could improve protein digests for mass spectrometry analysis.

New Assay to Study SARS-CoV-2 Interaction with Human ACE2 Receptor

Posted on by Promega

Severe acute respiratory syndrome (SARS) is a viral respiratory disease caused by a SARS-associated coronavirus. The most recent version, SARS-CoV-2 was first detected in China in the winter of 2019 and is responsible for the current COVID-19 (coronavirus disease 2019) global pandemic. This virus and its variants have resulted in over 200 million infections and more than 4 million fatalities world-wide. To combat this deadly outbreak the global research community has responded with remarkable swiftness with the development of several vaccines and drug therapies, all produced in record time. In addition to vaccines and drug therapies, diagnostic kits and research reagents continue to roll out to track infections and to help find additional therapies.

This peer-reviewed paper published in Nature Scientific Reports by Alves and colleagues demonstrates how a new assay can be used to discover novel inhibitors that block the binding of SARS-CoV-2 to the human ACE2 receptor as well as study how mutations in the SARS-CoV-2 Spike protein alter its apparent affinity towards human ACE2. The paper also details studies where the assay is used to detect the presence of neutralizing antibodies from both COVID-19 positive samples as well as samples from vaccinated individuals.

Inventory Managment and Onsite Stocking without the Headache

Posted on by Promega

The Helix on-site stocking program has been a resource for scientists for many years. With customized onsite stocking, inventory management and automated billing, losing precious time to a missing reagent is a thing of the past.

Helix freezers and cabinents provide seemless onsite stocking and inventory managment

To better understand the impact of Helix on our customers’ research, we spoke to Chris Thompson of Pro-GeneX, a clinical laboratory in Atlanta, GA. “Using the Helix system has been a game changer from the first day we got it,” Chris said.  “It was simple to set up and use from the start and has never let us down.  We routinely show it off to visitors to our lab because we are so impressed with it.  I only wish all my reagents used a system like this.  From an inventory perspective it is the best invention in our lab!”

Writing to PIs and hiring managers is a new experience for me, and one that is interesting to reflect upon as I will soon be graduating college and pursuing a career myself. I think it is important that PIs and potential employers understand my fellow undergraduates and recent graduates. This is crucial to ensure that they can find a fitting job for themselves, while employers also benefit by hiring an individual that will fit in to the work environment and make positive contributions.

Racing Against the Clock, University of St Andrews iGEM Team Engineers Safer Sunscreen

Posted on by Promega

Today’s blog was written in collaboration with Julia Ashley and AJ Ridley.

This August marked the end of a frantic 10 weeks of laboratory experiments for Julia Ashley and AJ Ridley. The two are members of the University of St Andrews iGEM team and are working to develop a product called Shinescreen, a probiotic sunscreen that is safe for marine life.

“Experiments were coming along nicely until the last two weeks in the lab. We ran into trouble with some transformation experiments,” said Ridley.

The team was on the clock, with only two and a half months of access to a laboratory. Unfortunately, the team’s time ran out before they could resolve all the issues.

“We learned the realities of science that not everything goes the way you think it will,” said Ashley. “But we got some results, and we’re happy with that.”

Today’s blog was written in collaboration with Melissa Martin, a global marketing intern with Promega. She is a senior at the University of Wisconsin-Madison where she is double majoring in zoology and life sciences communication, with a certificate in environmental studies.

In the best circumstances, leftover cooking oil ends up in a recycling center and is eventually burned as a biofuel. But it is also frequently dumped down kitchen drains where it proceeds to pollute sewage, water treatment facilities, and waterways.

Is there a more valuable and less harmful way to use up waste cooking oil? A group of students at the University of Málaga thinks they have a solution that will also make science more approachable and exciting for children.

Schools, businesses and organizations across the globe are increasingly implementing sustainable practices within their workspaces. From large-scale projects like installing solar arrays to behind-the-scenes initiatives like composting cafeteria food waste, “going green” is a reality of the modern workplace.

But one workspace otherwise known for being cutting edge and innovative is still struggling to implement the practices and culture of sustainability.

In her role as a teaching lab coordinator at the Johns Hopkins Institute for Nanobiotechnology (INTB), Christine Duke noticed a contrast between campus-wide sustainability initiatives and research labs:

“There is something missing here. Why aren’t we doing anything in the labs?”

Mentally Preparing for My Return to the Lab: A Grad Student’s Perspective

Posted on by Promega

Today’s guest blog is written by Sophie Mancha, a global marketing intern with Promega this summer. She will be starting her 4th year as a PhD candidate in the Biomedical Engineering Department at the University of Wisconsin-Madison, studying pancreatic cancer.

Graduate students are used to working. Not only during regular work hours but also well into the night to finish readings or work on data analysis. Ripping graduate students away from their research as they desperately try to produce useful data may be as hard as finding toilet paper during the first few months of the SARS-CoV-2 outbreak. However, across the world graduate students saw their research come to a screeching halt. The pandemic took over and everyone suddenly went into quarantine.

I clearly remember my first virtual lab meeting. We all frantically tried figuring out what video-conferencing platform to use and how to share our screens. We kept repeating “stay calm” as we naively thought this would only last a couple of weeks. As the months went by, I began to panic. I realized I had finished analyzing the last remaining data I had left and was no longer being “productive”. This quickly spiraled into thoughts that I may never earn my PhD.
