Comprehensive services in support of advanced development programs

Large Molecule Bioanalysis / Biologics and Bioassays

Gain access to comprehensive biologics services in support of advanced development programs with Frontage’s bioanalytical laboratory. We have the capabilities to analyze virtually any peptide, protein, or antibody, and have built a reputation for solving technical challenges related to assay development and validation.

Frontage’s biologics teams have an average of 10 – 15 years in complex drug development and have worked with large molecule applications throughout its evolution in product development. We can handle projects for a range of large molecule development projects including peptides, proteins, monoclonal antibodies, bispecific antibodies, biosimilars, oligonucleotides, biomarkers, and antibody-drug conjugates.

  • Esoteric and complex assay development
  • Labile compounds
  • Tissue sample analysis
  • Antibody-Drug Conjugates (ADC)
  • Determination of drug/antibody ratio (DAR) for ADC projects
Biologics and Bioassays
