High throughput DAR determination of brentuximab vedotin (Adcetris®) by reducing the analysis time

Drug-to-antibody ratios (DAR) of antibody-drug-conjugates (ADCs) such as brentuximab vedotin is important for their therapeutic efficacy and pharmacokinetics. Therefore, control of DAR is a key factor for ADC quality control. Given that, it is important for QC purposes to obtain a satisfying resolution of all DARs and the resulting average ratio whilst performing the separation in the shortest time.
