Bioanalysis of antibody drug conjugates using hybrid LBA/LC-MS and the BioBA Solution



Antibody drug conjugates (ADCs) represent a challenge for bioanalytical scientists, due to their inherent heterogeneity (i.e., different Drug-to-Antibody Ratios), high molecular weight,  presence in complex biological matrices and changes in ADC composition in biological samples. In addition to traditional immunoassay based methods, LC-MS is a powerful and efficient technology for ADC bioanalytical quantitation. This webinar will examine different methodologies for the bioanalysis of ADCs, and will highlight a hybrid LBA/LC-MS/MS assay using the SCIEX BioBA Sample Preparation Kit that enables a selective, immunocapture-based workflow with magnetic beads. This kit-based strategy allows users to develop sensitive and reliable bioanalytical assays with a wide linear dynamic range, with a simple step-wise protocol.

What will you learn?

  • Different assay techniques for ADC bioanalysis by LC-MS
  • Development of a LBA/LC-MS/MS assay for the quantitation of ADCs
  • How the SCIEX BioBA Solution provides an easy-to-use workflow for biologics quantitation

Who may this interest?

  • Bioanalytical scientists transitioning from small molecule to large molecule bioanalysis
  • Biopharma/CROs performing biologics and ADC bioanalysis
