Discovery Bioanalysis

Understand the pharmacokinetics and pharmacodynamics of your compound by quantification in biological matrices.

Discovery Bioanalysis is part of Cyprotex's portfolio of ADME PK services. Cyprotex delivers consistent, high quality data in line with Good Research Practice, and can adapt protocols based on specific customer requirements.


Cyprotex has a wide breadth and depth of experience in discovery bioanalysis for small molecules and bio-therapeutics including: peptides, oligonucleotides and targeted protein degraders. The scientific experience, capacity and application of the state-of-the-art bioanalytical equipment provide fast turnarounds that will help to arrive at “go/no-go” decisions faster. Our bioanalysis service is part of both standalone services as well as in vivo PK study packages.

Discovery Bioanalysis

Cyprotex offers non-GLP bioanalytical services with the option to qualify methods to support fit-for-purpose analyses.

Reliable and robust bioanalytical methods are critical for quantitative analysis. Developing a bioanalytical method requires an understanding of structural and physicochemical properties of the test compound as well as the matrix environment in which it is being measured. This is required to optimise the method and identify the most favourable detection, chromatographic separation and sample preparation techniques.

Our advanced bioanalytical method development and qualification service is used to demonstrate that a particular bioanalytical method used for quantitative measurement of analytes in a given biological matrix is reliable and reproducible for the intended analytical application. The fundamental parameters assessed include accuracy and precision, linearity, sensitivity, selectivity, recovery and stability.

For routine screening of compounds, we employ a number of generic LC-MS/MS optimisation and analysis procedures which guarantee high quality optimisation.

Discovery Bioanalysis Protocol


Data from the Discovery Bioanalysis


What is the typical workflow for liquid biological matrices?

Calibration standards (typically 1 to 5000 ng/mL), blanks, Quality Control samples (multiple replicates at appropriate concentrations to cover the analytical range) and incurred samples are subjected to protein precipitation or solid phase extraction and analysed by LC-MS/MS with incurred samples quantified from the calibration line.

What is the typical workflow for tissue analysis?

Tissue (typically 50 – 70 mg) is diluted with aqueous solvent and homogenised in a sample homogeniser. The homogenates are either analysed undiluted against matrix matched calibration standards or analysed against plasma/blood calibration standards respectively.

What are typical turnaround times for Discovery Bioanalysis at Cyprotex?

We aim to deliver Excel report format concentration data within 5 working days for liquid matrices and 10 working days for liquid matrices plus tissues. Please note that these times may vary depending on study and method complexity.
