Cell-based assays

Cell-based test systems realistically simulate the in-vivo situation and enable direct analysis of a cell reaction. We use vital mammalian cells as a diagnostic tool for our test systems. They are suitable for a wide range of test procedures in pharmaceutical research and in the development of new drugs, for example to investigate cell proliferation, toxicity, motility, and morphology. They thus enable targeted screening for new drugs and save time and money.

In addition to their use in drug screening, we have developed cell-based assay systems for the detection of pyrogens, e.g., bacterial residues that cause feverish reactions and even shock in humans. These are suitable for testing medical engineering devices and pharmaceutical formulations for pyrogenicity and can supplement or replace existing tests.

 

Cell-based test systems for determining biological parameters

Our non-clinical cell-based assays can be used to investigate various biological parameters of samples or substances.

Exemplary applications:

  • Testing of bioactivity, cytotoxicity, and immunogenicity of compounds using immune receptor-based assays
  • Screening of TLR agonists/antagonists
  • Testing of antimicrobial properties of substances or surfaces
  • Detection of pyrogens and microbial residues (pathogen-associated microbial patterns, PAMPs)
  • Detection of viruses

Our cell-based assays

This high-throughput assay can be used to screen substance libraries for substances with antifungal activity and, at the same time, for compatibility with human cells.

 

The test system enables quick and easy measurement of pyrogens on medical technology products, in pharmaceuticals, or in foodstuffs and supplements or replaces previous tests.

 

With the AVA, we analyze your samples for viral contamination or implement virus testing systems for your production processes.
 
 

In addition to AVA, we offer other cell-based test systems for determining the titer of cytopathic viruses in various samples.

TOPAS-Covid: Test system for investigating inhalation toxicological effects of airborne substances

Breathing through mouth masks, substances from the mask can enter the lungs via the inhaled air. To investigate the inhalation toxicological effects of such airborne substances, we established an in-vitro test system using a culture system of Fraunhofer ITEM and an adapted reporter cell line used for identification of allergy- and asthma-inducing effects.

Screening for new immunmodulators – Discovery and Delivery of PRR antagonists and agonists to regulate innate immune reaction

The receptors of the innate immune system recognize not only conserved molecular patterns of infectious pathogens, but also isolated chemical structures (PAMPs, pathogen-associated molecular patterns), and are referred to as pattern recognition receptors (PRRs).
