The Power of Two.
The Ease of One.
An ADC Manufacturing Alliance

Delivering What Matters, Together
With the development and clinical use of antibody-drug conjugates (ADCs) currently gaining significant momentum, the demand for contract development and manufacturing services continues to increase. In response, Simtra BioPharma Solutions (Simtra) and MilliporeSigma have forged a strategic alliance to streamline and accelerate the delivery of these targeted therapies and other bioconjugates to patients.
