Transforming the Pharmaceutical Industry with Biotherapeutics

Biotherapeutics have transformed the pharmaceutical industry over the last decade, thanks to their specificity and efficacy. Identifying potential biological drugs, developing them, and ultimately manufacturing them is heavily reliant on analytical science.1  

Pittcon is the ideal place for scientists in the pharmaceutical industry to learn more about the current and up-and-coming analytical techniques for characterizing biological molecules.  The  ‘Introducing the Analytical Challenges of New Biotherapeutic Drug Modalities’ symposium will outline the role of analytical science in biotherapeutics and introduce the popular analytical techniques in the field, along with state-of-the-art developments.2

Light scattering, bioassays, immunoassays, and spectroscopic techniques can all provide valuable information about biologics and are popular within the industry. If you are looking to learn more about the commercially available technologies, make sure you also visit the Pittcon expo, featuring industry leaders like Bruker, Waters, and Wyatt Technology, who can talk you through the best options.3-6

Techniques for protein separation and purification

Proteins are the molecular machines that do almost all of the ‘work’ in our cells. Proteins make excellent biotherapeutics because they can replace deficient or abnormal proteins, augment existing biological pathways, provide new functions, interfere with a molecule or organism, or deliver other compounds to targets in the body.7,8

Protein separation and purification often rely on differences in their solubility, size, charge, or absorption characteristics. Sometimes several separation techniques are used in sequence to separate all the proteins in a mixture fully.9

Pittcon will feature protein separation technologies, including dialysis, ultrafiltration, electrophoresis, and field-flow-fractionation. Chromatography of proteins will also feature heavily both in the expo and symposia, with topics including ion-exchange chromatography, affinity chromatography, size-exclusion chromatography, high-performance liquid chromatography, and ultra-high-performance liquid chromatography. The Pittcon expo will include all the major chromatography vendors including Shimadzu, Advion, and Walters.9

At Pittcon this year, Professor Daniel Armstrong from the University of Texas at Arlington will receive the LCGC Lifetime Achievement in Chromatography Award for his work advancing analytical techniques that are vital to the future of biotherapeutics. His presentation is entitled 'From Micelles, Chiral and Ionic Liquids to Ultrafast and Molecular Rotational Resonance Detection.10

Infinite selectivity protein chromatography

Chromatography of proteins is frequently limited by poor selectivity and resolution, resulting in peak overlaps. At Pittcon this year, the winner of the LCGC Emerging Leader in Chromatography Award, Professor Szabolcs Feket from the University of Geneva, will give a presentation entitled ‘Approaching Infinite Selectivity in Liquid Chromatography for Protein Separations.'11

He will describe his method for protein chromatography, which uses multiple columns with increasing retentivity combined with multi-isocratic mobile phases. Proteins are trapped in different columns, depending on their unique properties. They are then washed out using pulsed mobile phases, resulting in sharp, compressed peaks and tunable selectivity.11

Mass Spectrometry in Protein Science

Mass spectrometry, often coupled with other techniques like liquid chromatography, is a central technique in protein science, providing identification, sequencing, and quantification, even in complex mixtures. The Pittcon expo will feature all the major mass spectrometry instrumentation suppliers including Advion, Agilent, ThermoFisher, and many more.12-14

Ion mobility spectrometry-mass spectrometry (IMS-MS) combines ion mobility spectrometry, which separates molecules based on their mobility through a buffer gas, and mass spectrometry, which determines the mass to charge ratio of the separated ions. IMS-MS is one of few techniques that can help us study folding mechanisms, a topic that is key to protein engineering for new biotherapeutics.15-17

This year, Pittcon will feature a dedicated IMS-MS symposium (the Thirty-First James L. Waters Symposium). Professor David Clemmer from Indiana University will present a talk on ‘Mass-spectrometry based Strategies for Characterizing Native and Non-native Protein Structures,’ discussing his work studying protein folding mechanisms.18

Professor David H. Russell of Texas A&M University will give a presentation entitled 'Native Ion Mobility-Mass Spectrometry for Studies of Membrane Complexes.' His talk will outline his work developing next-generation, high-resolution IMS-MS machines.19

Protein analysis is unlocking the future of medicine

Protein analysis has a vital role to play in personalized medicine. Biologics have been described as the 'sniper' of the drug world, but they are only useful if they are targeting the correct biological pathway for each patient. Profiling patients, tailoring medicines, and observing their results all rely on sophisticated analysis. We need to continue pushing the boundaries of existing analytical techniques and developing new technologies so that we can reach a future where every patient receives the most effective drug for them straight away.20
