    The evolution of PCR: From q to dd and beyond

    The evolution of PCR: From q to dd and beyond

    PCR has evolved rapidly over the last few years, an evolution that has been dramatically accelerated by the COVID-19 pandemic. New technologies and approaches have been brought to the fore and the full range of applications for which this technique can be applied have been highlighted, from diagnostics to basic disease research and immunology.

    This episode explores this evolution, looking at how challenges presented by the pandemic forced the hand of researchers to think outside the box and build on lesser-known PCR technologies. Here, Eddy van Collenburg, Market Development Specialist at Bio-Rad, provides his insight into how ddPCR rose to prevalence during this time and explains how the technology is being used to enable trade, detect new variants and is being used outside of the pandemic.

    Discover the key role that ddPCR can play in gene therapy research, liquid biopsies, cancer research, single-cell studies and more, in this fascinating overview of the development of PCR and where the technique can go in the future.

    Revitalising the western blot

    Revitalising the western blot

    Love it or hate it, western blotting forms the bedrock of countless studies across numerous disciplines. Explore its history, development and applications in this episode all about the marmite of life science techniques.

    Guiding me through the hand wringing, hair follicle destroying history and process of western blotting, and hopefully explaining the beauty and potential of the technique - is Kenneth Oh, Senior Project Manager at Bio-Rad Laboratories.

    Kenneth reveals some of the latest developments in western blotting. Revealing how researchers are now able to validate the success of each stage of a western blot and work with smaller samples, Kenneth provides key tips for ensuring each of your western blots is a triumph.

    Molecular therapeutics: how far have we come and what is on the horizon?

    Molecular therapeutics: how far have we come and what is on the horizon?

    Uncover the history of molecular therapeutics, the staggering current applications and developments of these therapeutics and what their future could hold, in this episode of Talking Techniques.

    To explore the field of molecular therapeutics and provide an insight into their production, is Aaron Clauson, Product Manager at Zymo research. First, we cover the ins and outs of targeting the therapies and how to select the correct type of molecular therapeutic to begin developing a drug for a specific disease, before looking at some of the setbacks and safety errors that have occurred during the development of molecular therapeutics and how researchers have learned from these tragic events.

    Aaron also highlights the vital role of plasmids in almost all molecular therapeutic development, detailing the importance of keeping plasmid solutions and transfections free of endotoxins, revealing key solutions for avoiding these contaminants.

    Listen today to get all you need to know about molecular therapeutics, from their inception to their most exciting examples and how we can better communicate their benefits to the public in order to avoid mistrust and confusion - as has occurred during the COVID-19 pandemic.

    Adeno-associated viral therapies: harnessing the power of HPLC

    Adeno-associated viral therapies: harnessing the power of HPLC

    This episode centers on the critical role that high-performance liquid chromatography (HPLC) plays in the production of adeno-associated viral (AAV) therapies, the latest advances in AAV design and the next steps in their development.

    Filling me in on all things HPLC and AAVs is Bella Neufeld, Director of R&D at Teknova. Bella reveals the essential validation and quality control steps required for the production of successful and safe AAV therapies and the role that both HPLC and liquid chromatography–mass spectrometry (LCMS) play in these steps. We also explore the latest development targets for these therapies, looking at how AAVs can be targeted to specific sites and tissues before descending into the treacherous topic of reproducibility in the field.
