Bioanalytical Services

The bioanalytical team offers method development, method validation and sample analysis using state-of-the-art liquid chromatography and mass spectrometry (LC-MS/MS) and ICP-MS platforms. We conduct method validation and sample analysis in compliance with regulatory guidelines to support all stages of pharmaceutical development. 

Methods are developed and validated in accordance with either client-specific protocols or internal SOPs, and all methods are validated to meet appropriate and relevant regulatory guidelines. We are capable of handling both controlled substances (schedule 1 to 5) and radioactive materials, and have a large sample storage facility to serve as your biorepository.


Our current offerings include:

Discovery Support

  • Rapid method development of fit-for-purpose methods
  • Customized method qualification
  • High throughput analysis to support discovery TK/PK/PD studies and in vitro assays
  • Homogenization and analysis of tissues to assess drug distribution
  • Biomarker analysis for pre-clinical pharmacology studies

IND Enabling and Clinical Support

    • Method development
    • Method transfer and optimization
    • Full method validation per FDA/EMA/MHRA/ICH guidance
    • Cross-validations with partner laboratories
    • GLP sample analysis to support pre-clinical TK/PK studies
    • GCP standard sample analysis to support all phases of clinical trials
    • Clinical sample analysis to support bioequivalence studiesLARGE MOLECULE BIOANALYSIS

Technology Platforms & Techniques

We are capable of handling controlled substances (schedule 1 to 5), highly potent pharmaceutical compounds (OCH category 3 – 5), and radioactive materials. Additionally, we have a large sample storage facility to serve as your biorepository.
