Bioactivity Assays

Bioactivity of final products is an essential parameter in the specification of a biopharmaceutical drug substance. ORPEGEN's capabilities covers various technology platforms for assay development such as:

  • ELISA
  • Threshold™ (Molecular Devices)
  • FACS (Becton-Dickinson, FACSCalibur™)

Combined with our expertise in GCLP assay development, ORPEGEN has a track-record for establishment of qualified and validated methods used in product quality control. In addition, our know-how in immunology and routine-assay development has been successfully used to establish and monitor suitable in-vitro read-out parameters for pre-clinical or clinical studies. Our biological focus is put on :

  • Custom-tailored functional lymphocyte assays for analysis of migration capabilities, burst-activity, induction of degranulation, etc.
  • Custom-tailored NK cell cytotoxicity assays
  • Custom-tailored lymphocyte proliferation assays
  • Antibody-dependent cell-mediated cytotoxicity (ADCC) profiling
  • Evaluation of customer provided samples with our in-house research devices
