The CHROMacademy Essential Guide Webcast:
Techniques Employed in Biopharmaceutical Analysis – Part II Ion Exchange and SEC

Thursday 16th April 2015.

Biopharmaceuticals offer great new possibilities and potential in treating various life threatening diseases such as cancer and autoimmune diseases. However, their complexity, resulting from their heterogeneity, represents a great challenge to the analytical chemist and a suite of techniques is required in the characterization and analysis. In conjunction with RP and HILIC, covered in Part I, ion exchange chromatography (IEX) and size exclusion chromatography (SEC) are the main stay of the biopharmaceutical analyst’s arsenal. These techniques provide much more information than merely charge variance and aggregation analysis. In this event we will discuss how, why and where IEX and SEC are typically employed in biopharmaceutical characterization and quantification. We will also highlight strategies for developing more robust IEX and SEC methods such as reducing SEC secondary interactions and contrast the use of pH and salt gradients in IEX. We will also explore the affect temperature and pressure have on SEC separations and the role of UHPLC.

Presented by Dr. Davy Guillarme (Senior lecturer, School of Pharmaceutical Sciences, University of Geneva, University of Lausanne) and Scott Fletcher (Technical Business Development Manager, Crawford Scientific).

Biopharmaceuticals offer great new possibilities and potential in treating various life threatening diseases such as cancer and autoimmune diseases.  However, their complexity, resulting from their heterogeneity, represents a great challenge to the analytical chemist and a suite of techniques is required in the characterization and analysis.

We will also highlight strategies for developing more robust IEX and SEC methods such as reducing SEC secondary interactions and contrast the use of pH and salt gradients in IEX.  We will also explore the affect temperature and pressure have on SEC separations and the role of UHPLC. Finally an introduction, overview and applicability of Hydrophobic Interaction Chromatography (HIC) will also be covered.

Analysis of Post Translational Modifications Using LC-MS/MS Techniques Employed in Biopharmaceutical Analysis - Part I Reversed Phase and HILIC

Biopharmaceuticals offer great new possibilities and potential in treating various life threatening diseases such as cancer and autoimmune diseases. However, their complexity, resulting from their heterogeneity, represents a great challenge to the analytical chemist and a suite of techniques is required for their characterization and analysis. Reversed phase chromatography, the mainstay of traditional small molecule analysis, is employed at multiple biopharmaceutical levels due to its versatility, inherent relative efficiency and ease of hyphenation to a mass spectrometer.

HPLC Techniques in Biopharmaceutical Analysis

Biopharmaceuticals offer great hope in treating medical conditions which are currently poorly served at best by traditional pharmaceuticals. It is estimated that there are over 400 biopharmaceuticals in clinical trials for in excess of 200 disease areas. The enhanced complexity and variability that comes from the size of biopharmaceuticals, allied with the intricacy of the production process, mean chromatography is employed to a much greater extent during production and release testing. This Essential Guide webcast will provide details of why differing modes of chromatography are required in the research, preparation and analysis of biopharmaceuticals and when they would be typically used.

Analysis of Post Translational Modifications Using LC-MS/MS The Analysis of Post Translational Modifications Using LC-MS/MS

In this session, Dr. Duncan Smith and Dr. John Griffiths (MS-Insight Ltd and Manchester University) explain the principles behind the analysis of a number of key post-translational modifications (PTMs) using LC-MS/MS techniques. They will begin with a brief overview of bottom-up proteomics, explaining how proteins are converted to peptides, which are then analyzed using electrospray LC-MS/MS. They will move on to talk about the various MS scanning techniques, which may be used for PTM analysis. Next, they will discuss in turn, how phosphorylation, acetylation, ubiquitination and SUMOylation may be analyzed using mass spectrometry, drawing upon examples from their own research at the University of Manchester. Finally, they will give their own opinions on the ways in which they see the future of PTM analysis heading.
