Targeted protein degraders (TPD) are a relatively new therapeutic modality that opens the potential to target disease-causing proteins. These disease-causing proteins have been highly challenging for traditional small-molecule therapeutics to treat, making TPDs an exciting new therapeutic modality.
We are still developing our knowledge about TPDs and their behavior and optimizing analytical protocols to characterize and monitor them within the drug development process.
TPDs are typically dosed at low levels which makes their analysis in complex biological matrices challenging. Bioanalytical scientists who work with TPD compounds are striving to develop sensitive assays that reliably detect nanomolar concentrations of these highly potent drug candidates.

Metabolite identification (MetID) is a critical step in drug development due to its impact on drug efficacy and safety. LC-MS platforms provide good selectivity and sensitivity making it the preferred technique for MetID. Traditionally, LC-MS experiments have used collision-induced dissociation (CID) to fragment and identify the metabolites. With some metabolites, the fragment ions generated by CID do not always generate a conclusive result leading to alternative techniques being needed to meet the regulatory requirements. Deploying electron-activated dissociation (EAD) can help in these circumstances.
In this webinar, An approach to streamline and simplify the identification of crucial metabolites from targeted protein degraders, Ebru Selen explains how EAD can be used for MetID analysis, allowing scientists to:
Metabolite identification workflow
Electron-activated dissociation (EAD) is a fragmentation technique available on the ZenoTOF 7600 system that causes ions in an LC-MS/MS experiment to fragment in locations that differ from where they fragment with CID, providing additional information to scientists. For metabolite identification, this could mean confident localization of the site of metabolism, removing the need for further safety testing.

In a recent webinar, available on demand, scientists Luiza Chrojan and Ryan Hylands from Pharmaron, provided insights into the deployment of capillary gel electrophoresis (CGE) within cell and gene therapy. Luiza and Ryan shared purity data on plasmids used for adeno-associated virus (AAV) manufacturing and data on AAV genome integrity, viral protein (VP) purity and VP ratios using the BioPhase 8800 system.
Last year, Technology Networks hosted two webinars that featured groundbreaking research utilizing SWATH DIA (data-independent acquisition) for exposomics and metabolomics. Researchers Dr. Vinicius Verri Hernandes from the University of Vienna and Dr. Cristina Balcells from Imperial College London (ICL) demonstrated how a DIA approach can be successfully implemented in small molecule analysis using the ZenoTOF 7600 system. Their innovative approaches highlight the potential of SWATH DIA to enhance the detection and analysis of chemical exposures and metabolites, paving the way for new insights into environmental health and disease mechanisms.
For as long as PFAS persist in the environment, there is no doubt they will persist in our conversations as environmental scientists. Globally, PFAS contamination has been detected in water supplies, soil and even in the blood of people and wildlife. Different countries are at various stages of addressing PFAS contamination and many governments have set regulatory limits and are working on assessing the extent of contamination, cleaning up affected sites and researching safer alternatives.
