Moving from small molecule to large molecule bioanalysis by LC-MS/MS: A case study on challenges and techniques


The move to large molecule quantitation in pharma is accelerating, but for a small-sized CROs with extensive experience with small molecule bioanalysis, the shift can be challenging. This presentation gives you a first-hand look at the preliminary results from the lessons learned by SGS during their transition using the SCIEX BioBA Solution. This case study features the well-known biotherapeutic, Trastuzumab (anti-HER2 monoclonal antibody). You will hear how they overcame the challenge of finding specific signature peptides and optimization of chromatographic conditions. Plus, learn about their results with immunocapture using BioBA sample preparation kits.

What will you learn?

  • Practical tips for implementing a hybrid LBA-LC/MS quantitation technique
  • Real case study results using kit based immunocapture
  • Feedback from a CRO on transitioning from small molecule bioanalysis to biologics

Who may this interest?

  • Bioanalytical scientists in Biopharma/CROs performing quantification of large molecule analytes and biotherapeutics
