Benefit from our ultra sensitive PK/PD bioanalytical sample testing

Pharmacokinetics (PK) describe all processes that an administered drug is subject to in the body as a function of time, including absorption, biodistribution, metabolism and excretion.

Pharmacodynamics (PD) describe how the body responds to the drug in terms of biochemical interactions, like receptor binding or post-receptor effects. The resulting data give concentration time profiles of the drug and its metabolites, providing an understanding of what the body does to the drug.

This dose-response relationship is highly helpful to estimate the drug’s efficacy, duration, and safety, and thus to identify dosage and distribution for preclinical and clinical studies.


Our immunoassay validation is carried out as detailed by the guidelines for Bioanalytical Method Validation

        •  Federal Drug Association (FDA)

        •  European Medicines Agency (EMA)


We provide ultra sensitive bioanalytical support for modern biotherapeutics throughout all phases of drug development. Our immunoassay validation is compliant to GLP/GCP regulations and follows international industry guidance (FDA, EMA, ICH) to ensure that your bioanalytical method is well characterized, fully validated, and documented.

We also gladly assist you to select the most appropriate technology platforms for your research project and develop, optimize, and transfer PK assays to Imperacer®, Simoa®, MSD™ or ELISA.

From TOX to clinic

We have a long track record of supporting trials targeting a wide range of disease areas including oncology and neurology (CNS), as well as inflammatory, infectious, metabolic and rare diseases, in all phases of drug development


Rare matrices

We also have long-running experience in diverse and rare matrices, like serum/plasma, CSF, cell culture/medium, tissue extracts, mouse tail vein, tears, saliva, synovial fluid and many more. Virtually any matrix can be explored utilizing the Imperacer® platform's outstanding ability to maintain extreme sensitivity despite high sample dilution.


Combining broad quantitative range with excellent sensitivities, we are able to support biologics PK using a single assay format. From high dosing in TOX through extreme low dosing in dose-escalation to the later clinical stage, we provide regulated PK sample testing using validated methods, based on the same assay. This eliminates the need to run several assays to pair sensitivity and range.


As we have the capability to measure low concentrations of a given drug, we are able to provide a complete PK profile even for initial doses and thus shorten Phase I trials. Our high-quality data meet your regulatory requirements and can be decisive to evaluate ongoing dose escalation.
