ADC Product Characterization

ADC product characterization, testing, and assays for biotherapy development

Antibody drug conjugates (ADCs) that link monoclonal antibodies to deliver highly potent active pharmaceutical ingredients (HPAPIs) are inherently complex, making it imperative that you characterize your biotherapy to confirm its structure, binding, purity, and potency. As your characterization partner, we can provide expert guidance on the biological components of your ADC in both its “naked” and drug-conjugated versions – conducting safer, more reliable, and faster testing that helps to expedite product quality decisions at critical junctures.

Our ADC product characterization services feature: 

  • GMP compliant laboratories
  • Up-to-date regulatory advice and oversight
  • Cutting-edge technology and equipment
  • Experienced scientists and a dedicated project management team

Assays that de-risk development and manufacturing

The safety and effectiveness of your ADC starts with understanding the role played by the antibody in directing an ADC to tumor cells, as well as the potential for immune recruitment. Our broad range of assays for conjugated and unconjugated forms can help identify a variety of critical factors:

  • Antibody structure–function relationship
  • Desired quality attributes for its chosen application
  • Binding to the target antigen
  • Cytotoxic activity
  • Impact on efficacy following conjugation
  • Functionality following conjugation
  • Choice of linker used or the method of conjugation

See standard assay recommendations that can reveal your ADC’s structure, binding, and potency.
