End-to-End
Antibody-Drug Conjugate (ADC)
Development & Manufacturing

its range of services to include bioconjugation and the end-to-end
development and manufacturing of antibody-drug conjugates (ADCs).
Our standalone ADC bioconjugation facility is supported by the same robust GMP
systems that power our high-capacity clinical and commercial biological manufacturing,
ensuring the highest standards of quality, compliance, and efficiency.
Dedicated ADC Facility for Streamlined Drug Substance Manufacturing
- Our purpose-built ADC manufacturing site enables unified coordination from conjugation development to final formulation. This site features:
-
- Expedited drug substance (DS) delivery with flexibility at a single site
- Expertise in quality and proven operational track record
- Integrated systems with established tools and procedures
- Stable supply chain management system


Key Features of Our ADC Facility
-
Our ADC facility is equipped with single-use and stainless steel
reactors supporting up to a 500 L conjugation train, enabling
scalable and flexible ADC manufacturing. It includes full-scope
laboratories for ADC development, quality control (QC), and MSAT.
The facility is built to handle high-potency APIs (HPAPIs) with
stringent high-containment systems, achieving an Occupational
Exposure Limit (OEL) target of 5 ng/m³ to ensure safety and
compliance at every step.
Dependable ADC Services From a Trusted CDMO
We deliver end-to-end ADC services, from antibody production and conjugation development to full-scale ADC manufacturing.
As a leading ADC CDMO, Samsung Biologics ensures every stage of the antibody-drug conjugate lifecycle is supported with expert execution and regulatory precision.
