TechTalk: ADC characterization in one native LC-MS workflow
Friday, September 4 at 16:00 BST | 17:00 CEST | 11:00 EDT | 08:00 PDT
Achieving comprehensive antibody-drug conjugate (ADC) characterization no longer requires complex multi-step workflows. Advances in native LC-MS are creating new opportunities to simplify ADC analysis while maintaining the depth of information needed to support development decisions.
In this SelectScience® TechTalk, Roxana Eggleston-Rangel, Senior Applications Scientist at Phenomenex, will showcase how Biozen® Native RP-1 and RP-5 columns enable direct drug-to-antibody ratio (DAR) analysis through a streamlined, MS-compatible native reverse-phase liquid chromatography-mass spectrometry (RP-LC-MS) workflow.
Learn how this approach supports DAR determination, proteoform characterization, and positional isomer resolution without fraction collection or buffer exchange while maintaining native conditions.
Using case studies featuring the approved ADC therapies Enhertu®, Padcev®, Polivy®, and Adcetris®, Eggleston-Rangel will demonstrate how this workflow can be applied across a range of ADC modalities and payload chemistries. In just 20 minutes, discover how the same approach can support both high-resolution mass spectrometry and routine UV-based DAR monitoring, bringing greater efficiency and confidence to ADC characterization.
