• A clear picture – staining tips for gel electrophoresis

  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. Helpful resource links mentioned in this episode:A helpful DNA stain selection guideRNA stain options and detailsEffects of dyes on gel electrophoresis properties Subscribe to get future episodes as they drop and if you like what you’re hearing we hope you’ll share a review or recommend the series to a colleague.  Visit the Invitrogen School of Molecular Biology to access helpful molecular biology resources and educational content, and please share this resource with anyone you know working in molecular biology.

• With knowledge comes great responsibility

  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 each of the four levels of biosafety labs, but it quickly moves beyond, shining a light on the security and containment needs for more than just the organisms. We hear about how the data and methods used to do modern molecular biology, as well as the data generated in the experiments, are equally precious and in need of protection and containment. With public health and safety on the line, and an acknowledgement that the pace of science moves faster than that of policy, we get into the idea of who really owns responsibility for protecting data. Your role might be more important than you know, so don’t miss this conversation that will make you pause and think!

• DNA on the move – the influence of form on gel migration

  Agarose gel electrophoresis is a staple method in almost all biology and biochemistry lab where separation and analysis of nucleic acids is needed. In this Mol Bio Minutes mini episode Augustė Užuotaitė, Scientist III at Thermo Fisher Scientific, covers the basics of electrophoresis with a spotlight on how different forms of DNA migrate differently in agarose gel electrophoresis.In less than 10 quick minutes, you’ll learn about the many factors that affect DNA migration rate. Augustė reviews how DNA size, sequence, and conformation all affect migration rate, and she gives some beautifully simple examples to help it all make sense. Helpful resource links mentioned in this episode:Nucleic acid gel electrophoresis – summarized in 5 easy stepsFive important considerations for the nucleic acid gel electrophoresis Subscribe to get future episodes as they drop and if you like what you’re hearing we hope you’ll share a review or recommend the series to a colleague.  Visit the Invitrogen School of Molecular Biology to access helpful molecular biology resources and educational content, and please share this resource with anyone you know working in molecular biology.

• The genetics and neuroendocrinology of obesity

  Obesity is one of the most pressing health challenges of our time, with genetic and molecular factors playing a crucial role in how our bodies regulate weight. In this season opener, we explore the science behind obesity, focusing on how hormones, genetics, and brain circuits influence feeding behavior and body weight. Join us for a fascinating discussion about the interplay between molecular biology and real-world health outcomes.Our guest, Dr. Giles Yeo, is a professor of molecular neuroendocrinology at the University of Cambridge and an expert in the genetics of obesity. With decades of research experience, Dr. Yeo dives into how hormones like GLP-1 interact with the brain and how genetic mutations can affect eating behaviors. He also explains the innovative molecular biology techniques his lab uses to map brain circuits and decode the genetic influences on body weight.But this episode isn’t all about the lab. Dr. Yeo shares his journey from studying the genetics of Japanese pufferfish to becoming a leading voice in obesity research and science communication. Whether he’s decoding how Ozempic works or reflecting on the importance of good science communication, Dr. Yeo’s passion for the field—and his knack for making complex topics relatable—shines through.
