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 your lab, time is not just a resource. It’s a necessity and every moment counts. Yet, unplanned downtime can disrupt this delicate balance. Even a brief interruption can set your team back in multiple ways.
In a recent webinar, which is now available on-demand, Holly Lee powerful strategies to tackle complex residue testing. From boosting throughput to fine-tuning method sensitivity, Holly shared key ways to maximize performance across large pesticide panels.
Whether we are raising glasses of rosé in a vineyard in France or enjoying a lager in a casual street restaurant in China, it is likely that the last thing on many people’s minds is the chemical risks from their beverage. Unless you work in food science, then it might actually be the first thing.
