Bioanalysis for Small Molecules

We provide the following services for small molecule bioanalysis:

Regulated Bioanalysis

  • Method development, GLP validation, and transfer, using LC/MS/MS (HPLC, UPLC, 2-D Chromatography), HPLC/UV, and HPLC/Fluorescence techniques.
  • GLP sample analysis and clinical sample analysis, to support toxicokinetic, tissue distribution, Phase I-IV, clinical pharmacology, drug-drug interaction, and BA/BE studies.

Discovery Bioanalysis (non-GLP)

  • Method development, using LC/MS/MS, HPLC/UV, and HPLC/Fluorescence techniques.
  • Non-GLP bioanalysis and pharmacokinetic (PK) screening, to assist with lead candidate selection decisions and to support discovery PK and early preclinical studies.
  • Methods can later be adapted and validated for regulated preclinical and clinical studies.

High-Throughput Bioanalysis

  • For sponsors needing high-throughput bioanalysis of clinical study samples, we have 25 LC/MS/MS systems, most coupled with UPLC systems, and the capacity to inject at least six plates of samples unattended.

Pharmacokinetic Analysis & Reports

  • Model dependent or model independent PK/TK analysis of bioanalytical data from discovery, preclinical, GLP toxicology, and clinical studies.

Method Development & Validation for Small Molecule Bioanalysis

We provide full method development and validation for the analysis of small molecules. Our scientists approach every compound with creativity, innovation, and years of scientific knowledge, allowing us to uncover solutions to complex bioanalytical challenges.
