    From prototype to production – solving the scale-up gap

    Great science doesn’t always translate into a scalable product, and that gap can stall even the most promising innovations. In this Mol Bio Minutes episode, Steve Lewis explores a common challenge in biotech: moving from a validated assay or prototype to a commercially viable product. While scientific teams often achieve strong early results, scaling requires coordination across design, engineering, materials, and manufacturing, which typically involves multiple vendors. This fragmented process introduces delays, misalignment, and risk. The episode highlights how physical product design, especially for consumables like microfluidic cartridges or custom plastics, can ultimately determine whether a solution reaches the market. By integrating design, prototyping, and manufacturing under one roof, Thermo Fisher Scientific’s Plastics Prototyping Services aim to streamline this transition. Early consideration of materials, manufacturability, and reagent compatibility enables faster iteration and more efficient scale-up, particularly for startups navigating growth stages. Ultimately, the message is clear: if your biology works but your product doesn’t scale, the problem is solvable. With the right integrated approach, innovation doesn’t have to stall, it can move efficiently from idea to impact.

    The real cost of PCR - beyond price per reaction

    Not all experiments are created equal, and neither are the decisions behind them. In this episode, Cam Cyr explores how scientists navigate the balance between cost and performance in molecular biology workflows. Drawing from his experience as a technical sales specialist, Cam breaks down what “performance” really means in practice, from enzyme fidelity and sensitivity to reproducibility and inhibitor tolerance. He highlights how these factors become critical in high-stakes applications like antibody engineering or single-cell analysis, where errors can propagate and compromise entire workflows. Through examples like reverse transcription enzymes and high-fidelity polymerases, Cam illustrates why premium products are often essential when working with rare samples or build-critical steps. At the same time, he explains where cost-saving approaches make sense where results are binary and easy to replicate, such as genotyping or routine screening. Ultimately, the conversation reframes how scientists should think about cost, not as price per reaction, but as cost per successful result. Along the way, Cam shares his career journey from bench science to a customer-facing role, offering perspective on the many paths available in life sciences and the importance of staying curious.

    The molecular toolkit behind HIV research

    HIV research is one of the clearest examples of molecular biology in action. In this Mol Bio Minutes episode, Dr. Ryan Jeep walks through how fundamental molecular techniques power everything from detection to drug resistance studies to cure-focused research. Ryan begins with HIV biology and detection, explaining how qRT-PCR enables highly sensitive viral load measurement. These assays not only detection strategies but also support research to monitor treatment efficacy and viral rebound. From there, he moves into drug resistance, describing how sequencing, RT-PCR, and cloning strategies help researchers map resistance-associated mutations. By generating recombinant reporter viruses and measuring infectivity against different drugs, scientists can better understand treatment failure and move toward more personalized therapeutic strategies. Finally, Ryan explores cutting-edge cure research, including CRISPR-Cas9 approaches aimed at either disabling integrated viral genomes or engineering HIV-resistant immune cells. Across all three areas one theme remains constant: PCR, sequencing, and cloning form the technological backbone of HIV research. As these tools continue to evolve, so too does the potential to improve outcomes and one day eliminate the virus entirely. Since recording this episode, Ryan has joined KBI Biopharma as a Scientist l in their Formulation Development Group.

    DNA-encoded library use in living cells for drug discovery

    In this episode of Speaking of Mol Bio, host Steve Lewis speaks with Dr. Leif Larsen, Director of Biology at Vipergen, about the power of DNA-encoded libraries (DELs) in modern drug discovery. DEL technology enables researchers to screen extremely large chemical libraries by attaching a unique DNA barcode to each compound, allowing millions, or even hundreds of millions, of compounds to be analyzed simultaneously through sequencing.  Larsen explains how Vipergen’s platform flips traditional screening methods by storing massive compound libraries in a single tube and identifying binding interactions through DNA sequencing. He also describes their proprietary Binder Trap Enrichment (BTE) method, which links DNA barcodes when compounds successfully bind their protein targets. One of the company’s most innovative advances is performing DEL screening inside living Xenopus oocytes. By expressing target proteins in these large cells and microinjecting DNA-encoded libraries, researchers can evaluate binding events in a physiologically relevant environment. The discussion also explores how this technology accelerates early drug discovery timelines and enables screening of difficult targets such as transcription factors and membrane proteins. Larsen closes by highlighting emerging areas such as PROTAC-based targeted protein degradation and how DEL screening can help identify molecules suitable for these next-generation therapeutic strategies.

  5. Choosing the right PCR method for your experiment

    Choosing the right PCR method for your experiment

    In this Mol Bio Minutes mini-episode of Speaking of Mol Bio, Dr. Andrea Hunger walks listeners through the practical differences between three core PCR approaches: endpoint PCR, quantitative PCR (qPCR), and digital PCR. Drawing on her experience in both academic research and industry, she explains how each technique provides different types of information and why choosing the right one depends on the biological question being asked.  Endpoint PCR is the simplest method and is ideal for basic presence-or-absence questions such as confirming cloning success or genotyping samples. While fast and accessible, it does not provide quantitative information. For experiments requiring measurement of gene expression levels or comparisons between samples, qPCR offers a powerful solution by monitoring amplification in real time and using Ct values and standard curves to estimate starting concentrations. Hunger then discusses digital PCR, a newer technology that partitions samples into many micro-reactions to enable highly precise, absolute quantification of nucleic acids. Because it counts positive and negative partitions directly, digital PCR is especially valuable for detecting rare mutations, low-abundance targets, and applications like liquid biopsy analysis. Ultimately, she emphasizes that these PCR approaches are complementary tools, and the best experimental strategy is to choose the method that provides the level of information required for the next step in a research workflow.

    From bench to bushland ─ developing a koala chlamydia vaccine

    In this Season 4 premiere of Speaking of Mol Bio, host Steve Lewis speaks with Dr. Nina Pollak from the University of the Sunshine Coast about the development of a single-dose vaccine aimed at protecting endangered koalas from Chlamydia pecorum. The disease is a major threat to koala populations across eastern Australia, contributing to infertility, blindness, and increased mortality. Pollak’s work focuses on optimizing the production and quality control of vaccine antigens while supporting regulatory approval and field trials that ultimately led to a conditional minor-use permit from Australia’s veterinary regulatory authority.  The vaccine relies on recombinant versions of the major outer membrane protein (MOMP) from three dominant chlamydial genotypes. Using standard molecular biology techniques, including gene cloning in E. coli, His-tag purification, SDS-PAGE verification, western blotting, and mass spectrometry, Pollak’s team produces and verifies these vaccine antigens before combining them with adjuvants to stimulate protective immune responses. Beyond the science, the episode explores the challenges of conservation-focused vaccinology: field vaccination of wild animals, limited commercial incentives, and the importance of methods for monitoring disease prevalence. Pollak also reflects on the collaborative nature of the decade-long project and offers advice to young scientists pursuing difficult but meaningful research challenges.

    How RCA supercharges NGS library prep

    In this Mol Bio Minutes mini-episode, Laurynas Alijošius shares how Rolling Circle Amplification (RCA) provides a reliable, high-yield approach for amplifying circular DNA prior to next-generation sequencing (NGS). This isothermal method avoids the need for thermal cycling and even bypasses the need for specific primers—making it ideal for challenging viral genomes, rare targets, or field samples. Powered by the strand-displacing phi29 DNA polymerase, RCA amplifies DNA with impressive sensitivity and minimal GC bias. Laurynas breaks down the steps of multiple displacement amplification (MDA), explains why exonuclease-resistant primers are important, and explores how engineered polymerases like EquiPhi29™ DNA Polymerase dramatically improve yield and reduce reaction times. RCA products can be cleaned up and debranched to support a range of downstream workflows, including nanopore sequencing and transcriptomics. From single-cell genomics to phage-based applications and in vitro expression systems, RCA is more than just a pre-NGS step; it’s a versatile tool with broad utility. Whether you're stabilizing viral RNA or tackling ultra-low-input samples, RCA and whole genome amplification offer new flexibility for today’s demanding sequencing workflows.
