TechTalk: Bioanalytical strategy for parallel total and conjugated antibody quantification for novel ADCs
Thursday, September 24 at 16:00 BST | 17:00 CEST | 11:00 EDT | 08:00 PDT
Antibody-drug conjugates (ADC) are a rapidly expanding class of therapeutics, especially within oncology. The complex nature of the ADC requires additional pharmacokinetic (PK) assays, including quantification of total antibody (tAb) and conjugated antibody (cAb).
In this Tech Talk, Dr. Valeria Castagna from Merck, Italy, will describe how parallel testing and validation of assays to measure tAb and cAb on Gyrolab®, saved time and sample volumes in ADC drug development, without compromising the data quality.

What will this webinar cover?
- How a large pharmaceutical company adopts a parallel validation strategy for simultaneous tAb and cAb method validation on Gyrolab® – including the single MRD preparation approach, plate-splitting workflow, and how multi-run instrument configurations (Gyrolab xPand or multiple xPlore units) support same-day execution.
- How the company achieved efficiency gains from parallel vs. sequential validation – validation time reduced by approximately half, matrix and reagent consumption halved, and fewer operators required over a shorter engagement period.
- Insight into total antibody (tAb) and conjugated antibody (cAb) as separate bioanalytical analytes in ADC programmes – understand what each measures, why both are required, and how they relate to DAR distribution and in vivo payload stability.
