Service offering

Pre-clinical drug screening and toxicity screening.

Our advanced data processing methods of interpreting zebrafish behaviour allow for fast, accurate and cost-effective results when assaying a wide spectrum of diseases or toxicity.

Screening assays

ADHD assay
Epilepsy assay

Our epilepsy assay is used to screen for the effects of compounds in anti-seizure medicine.

What makes our approach stand apart is how we use behavioural models in zebrafish to select the most promising compounds.

The epilepsy assay consists of 3 separate steps:

  1. Test for seizure control

2. Toxicity screening



3. Verification

Sleep assay

Our sleep assay allows you to very effectively evaluate the actual sleep-inducing effects of different drug compounds.

The 3Z Sleep Assay analyzes (in a single run) the sleep effects of 48 different pharmaceutical compounds

Here we identify the highest scoring sleep-inducing compounds - and then we run them through again for confirmation and further analysis.

Preclinical drug screening

Preclinical drug screening assays with zebrafish models can dramatically increase cost-effectiveness in the early phases of drug development.

3Z Pharmaceuticals’ use of the zebrafish platform, coupled with our exclusive methods in behavioural modelling and data analysis, make our company a valuable partner in the speeding up of your drug pipeline.

Toxicity screening

Tox assays need to be clear and accurate – and sometimes getting the results is urgent, too. We provide for all these needs with our catalog or tailor made tox-assay solutions, giving you reliable in vivo results on the toxicity of the compound in question.

Tailor made screening

In addition to our in-house assays we can develop customized assays to suit your needs in screening for particular compounds.
