Activity Assays

Different formulations and conditions of an active product may have a huge impact on its biological activity. Activity assays can be developed and validated to quantify the biological activity of your product (comparison or monitoring of lot to lot, formulation difference, etc.)

Examples of activity assays:

  • Cell-based potency
  • Antibody-dependent cell-mediated cytotoxicity (ADCC)
  • Complement-dependent cytotoxicity (CDC)
