As one of the most promising in-vivo gene delivery vectors, adeno-associated virus (AAV) has been widely used in various gene therapy products. In order to ensure the safety and efficacy of these AAV-based gene therapy products, it is crucial to understand and measure their critical quality attributes (CQAs) throughout the development cycle. In this podcast, we will discuss how to apply a well-established bio-therapeutics characterization tool, SEC-MALS (size-exclusion chromatography combined with multi-angle light scattering and other online concentration detectors), for quantifying AAV CQAs. This SEC-MALS method has been recognized and demonstrated as a robust, sensitive, and automated assay for AAV development platform and production release testing.
Kirstine Nielsen of Aarhus University (Denmark) discusses how targeted metabolomics ratios helped build a robust bloodstain time-since-deposition tool.
Gérard Hopfgartner explains how atmospheric pressure photoionization can generate radical cations in LC–MS, unlocking EI-style spectra and NIST's spectral library.
LCGC International spoke to Akina Nara of Japan’s Tohoku Medical and Pharmaceutical University about a new study which links a blood compound to how long a body has been dead.
A method coupling gas chromatography-tandem mass spectrometry (GC-MS/MS) and multiple reaction monitoring (MRM) tracks lipid markers of decomposition in commingled remains.
This week's top stories on the Chromatography Online website spotlight LCGC International's new SFC-focused interview series charting the technique's rise alongside LC and GC, complemented by a practical GC data-reporting refresher and a study using chromatography to detect trace pesticides in tap water.
