LCGC Asia Pacific February/March 2020 Regular Issue PDF

LCGC International sat down with Katarina Marakova to discuss her group’s work in top-down analysis of proteins using capillary zone electrophoresis–mass spectrometry (CZE–MS).

Experts from academia and industry present on the innovative research projects they are working on.

This application note showcases a Biozen dSEC-7 SEC chemistry/fluorescence detector solution, offering reliable AAV aggregate analysis in under 10 minutes with as little as 0.5 µL of sample. Across four AAV serotypes, resolution between monomer and aggregates remains consistently high, emphasizing Biozen dSEC-7's efficiency and ability to maintain accurate detection at minimal injection volumes. Ideal for routine testing, this solution ensures precise measurement of a CQA with streamlined sample consumption.

With its 700 Å large pore silica particle and hydrophilic diol-type surface chemistry, Biozen dSEC-7 provides excellent resolution of monomer from dimer peaks in under 8 minutes across four different AAV serotypes. This capability is crucial for optimizing gene therapy biopharmaceuticals, ensuring thorough analytical scrutiny to select the most appropriate serotype(s) for enhanced therapeutic outcomes and immunogenic profiles.
