Over the past 20 years, protein and peptide drug development has evolved considerably and made a significant impact on the biotherapeutic market. This expansion into biologics has pushed pharmaceutical companies and contract research organizations (CROs) to explore new approaches for efficiently quantifying these large molecules to support high throughput, early stage pharmacokinetic (PK) studies. The gold standard has been ligand binding assays (LBA), but liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) is emerging as a promising alternative for biologics quantification.
Especially for compounds in early stages of drug development, LC-MS/MS offers multiple advantages over LBA such as multiplexing capability, higher selectivity, and faster method development. In addition, LC-MS/MS is an attractive alternative at early stages since the availability of specific reagents needed for LBA assays can be limited.
This webinar will highlight current challenges and emerging opportunities for the discovery environment. Key areas of focus will include:
- Factors affecting the choice of LBA or LC-MS/MS for biologics quantification
- Considerations when selecting a top-down or bottom-up LC-MS/MS workflow for biologics quantification in the discovery environment
- Factors that should be considered when choosing an extraction method for LC-MS/MS quantitation of biologics
- Best practices when developing a robust discovery level method without a validation
- Future opportunities for biologics quantification within the discovery bioanalytical space
