Conjugation Process Development

The ADC conjugation process involves linking the drug payload to the antibody via a linker at a defined drug-to-antibody ratio (DAR). The primary objective of process development is to design an efficient process flow, optimize conjugation reaction parameters, and purify the target product while minimizing product-related impurities (e.g. aggregates and fragments) and process-related impurities (e.g., residual free drug and solvents).

Key Features of Our Conjugation Process Development Platform

  • Dedicated Lab: We have established a dedicated ADC laboratory equipped with a negative-pressure isolator and a biosafety cabinet, ensuring both operator safety and compound integrity during processing.

  • Experienced: Our team has successfully developed lysine, cysteine, and enzyme-mediated conjugation processes. By leveraging our expertise in reaction chemistry, we use both OFAT and DOE studies to design optimized processes tailored to your specific needs and objectives.
