With prior Mol Bio Minutes episodes covering DNA form migration and staining considerations for nucleic acid gel electrophoresis, we tie it all together with this great set of overall tips, tricks and resources for the topic. Anyone that’s ever run a gel has undoubtedly produced gels with smeared, faint or poorly separated bands. What causes these and how can you avoid them?  Well, Aistė Polikaitytė, Scientist at Thermo Fisher Scientific is here to cover the likely causes and troubleshooting tips to help avoid the most common gel issues. She touches on how much sample to load, the im...

It could be argued that biology has always boiled down to chemistry, and that chemistry has always boiled down to physics. However, not many would deny that the fields of biology and chemistry are overlapping more than ever, with both leveraging computing methods, also more than ever. This conversation with Dr. Ramesh Jha, Technical Staff Member at Los Alamos National Laboratory (LANL), crosses biology, chemistry, and computing methods. The work of his biome team at LANL uses computational tools to inform the design of enzymes that are produced via PCR-based cloning and then expressed in microbes. They u...

You can run the perfect agarose gel to separate your nucleic acid fragments but if you don’t stain and image the gel properly, it’s all for not. In this second installment of Mol Bio Minutes we take a look at the staining considerations for nucleic acid gel electrophoresis with Paulius Palaima, Product Manager at Thermo Fisher Scientific. He covers the range of stains and staining approaches available while calling out pros, cons and considerations for each. How these recommendations change, depending on your sample, is also covered in this approachable but informative episode. Helpfu...

Topics and terms such as biosafety, biosecurity, containment, and contamination are things most of us have heard of and think about at some level, but with the pace of molecular biology moving faster than ever, these are topics with implications that are reaching farther than ever. We’re joined by Dr. Ryan Burnette and Dr. Lauren Richardson from Merrick and company for this episode, and they’re ace communicators that help walk us through the expanding horizon and implications of these topics.This conversation starts on the basic topics, like what biocontainment is and what’s needed for ea...

We’re joined in this episode by Dr. Sarah Barry, Reader in Chemical Biology at King’s College London. Sarah started with an interest in biochemistry, went into organic chemistry because it was more concrete, and now applies her chemist’s approach to understanding and manipulating biosynthesis of natural products for important areas of research, including antibiotics. This insightful conversation gives a peek into the mind of a chemical biologist’s way of thinking about and approaching challenges that span biology and chemistry. We learn about the historical challenges of discovering and synthesizing natural products, but we then hea...

The history of fermented foods like beer, bread, and other foods can be traced back thousands of years to ancient civilizations in China and Egypt. This ancient technology was originally used to preserve foods when refrigeration was not an option. While less common in modern industrialized civilizations, we’re now realizing that fermented foods play a major role in gut microbiome diversity, which is a biomarker for overall health. Join our conversation with Dr. John Leech, Technologist at Teagasc in County Cork, Ireland to learn all about the history and how cutting-edge technologies are being applied to re...

While some of us knew a good bit about mRNA prior to 2020, we all got a crash course on mRNA technology and its prophylactic and therapeutic potential as a result of the COVID pandemic and subsequent SARS CoV-2 vaccine development. In fact, most of us have now received at least one mRNA vaccine at this point. Our guest for this episode, Dr. Christian Cobaugh, Co-founder and CEO of Vernal Biosciences, was a passionate believer in mRNA medicines well before the pandemic. Join us to hear his story and his passion for this technology. He walks us through...

There are all sorts of molecular tests to tell if you’re infected with something specific, but what do you use when you’re not sure what you might have? You might use a thermometer as a first step, but wouldn’t it be nice if that thermometer was a bit more high tech? In this episode we meet Dr. Nick Meyerson, CEO and co-founder of Darwin Biosciences, who’s team is working to develop the “molecular thermometer of the future.” We hear about how this physicist transitioned into molecular biology and then latched onto saliva as a sample of...

Plastics are a modern miracle of science that have helped deliver both convenience and life-saving solutions. However, we must now grapple with the challenge of immense amounts of plastics in our waste streams and environment. How do we best deconstruct plastics to reusable or more bio-friendly molecules? This is the exact challenge being addressed by the work of Dr. Elizabeth (Izzy) Bell and her team at the National Renewable Energy Lab. Our conversation with Izzy showcases her ability to summarize complex topics very concisely and understandably, which she says is a skill that is critically important in...

Most scientists start their education and careers with a vision of working in the lab to discover great things and drive innovation. However, we don’t all end up loving the actual lab work portion of science. What non-lab career options exist to utilize molecular biology knowledge and skills? Well, according to our guest, Jason Amsbaugh, Founder and CEO of Samba Scientific, the career options are far more plentiful than you may think. Scientific marketing, according to Jason, is one such role that is all about understanding the science, first and foremost, but it’s also about effe...

While the end product is quite different, brewing beer is not all that different than many other bioproduction processes used in the lab and industry. Both require skills, experience, and the right QC/QA methods to control and monitor the starting materials and the entire process, all the way to that bottle of suds you might be thirsty for. Steve and Gabriel talk with Kelly Tretter, a microbiologist with more than 30 years of experience in the brewing industry, to discuss brewing at the molecular level. The passion of all three for beer is evident in the conversation...

When you buy chicken or turkey from the grocery store, you might not give it much thought, but there is an entire network of people working to ensure the health of the animals in our food supply chain and your health. In this episode, we talk with an unsung hero, Beverly Wood, supervisor of the molecular diagnostics lab at the North Carolina Department of Agriculture and Consumer Services, who works tirelessly to ensure the health and safety of poultry and livestock animals in our food supply chain.
