planar chromatography revolution in effect directed analysis

This is our expertise…

Research & Validation

We help you identifying what works for your application and develop customized assays and procedures. Our expertise in validation is key to your success in effect-directed analysis.

Industrialization

We believe that planar effect-directed analysis and bioautographic methods need a high level of standardization. our mission is the prototyping of ready to use planar test kits.

Know-How Transfer

We offer hands-on workshops and training as well as consulting in planar method establishement.

Lab-Services

Our fully equipped service lab and our experts await your samples and analysis requests

Bioautography & Effect-Directed Analysis

Our Technology: planar Bioassays

planar Effect-Directed Analysis p-EDA is the combination of separating multicompound mixtures and assessment of their bioactivity in one method. The reproducibility of the planar chromatographic separation as well as the exclusion of possible artefacts by including suitable controls is key for success of planar bioassays.

planar Yeast Estrogen Screen (pYES)

The reporter gene assay for the human estrogen receptor α in recombinant yeast cells, offers rapid and sensitive detection of endocrine antagonists: it detectd endocrine disruptors in water as well as phytoestrogens in food and herbs.

planar Enzyme Inhibition Assays

Detection of Enzyme Inhibitors are relevant in actives development as well as in toxicological assessment. We offer rapid colorimetric planar enzyme assays for multiplex samples: e.g. Xanthine Oxidase, Acetyl- und Butyryl-Cholin-esterase,  α/β-Glucosidase, Lipase. etc.
