Enhancement and Optimization of Our Test Systems

November 17th, 2017|Comments Off on Enhancement and Optimization of Our Test Systems

We are determined to extend the application range of our yeast-based tests, particularly those aimed to be used for measuring endocrine disruptive effects of environmental contaminants. We are still always improving the performance of [...]

Endocrine disruption in Antarctic waters

December 14th, 2016|Comments Off on Endocrine disruption in Antarctic waters

  Chemicals that exert endocrine effects in organisms, commonly referred to as endocrine-disrupting compounds (EDCs), have become a growing concern in recent years. Exposure to EDCs is currently regarded as one of the most serious [...]

ISO standardization of the A- YES® – A standardized method for detection of estrogens in water

April 2nd, 2016|Comments Off on ISO standardization of the A- YES® – A standardized method for detection of estrogens in water

There are no limits to testing the estrogenic activity of environmental samples because there is no shortage of estrogen-like substances (ex. Bisphenol A) to investigate and no laws regulating their presence in water. This problem [...]

Development of an online-multisensor system

January 19th, 2012|Comments Off on Development of an online-multisensor system

The aim of this research project is the development of a semi-autonomous system for on-site measurement and detection of endocrine-disrupting substances in municipal wastewater treatment plants. Contamination of our water supplies with incompletely metabolized pharmaceuticals [...]

Effect-based trigger values for in vitro and in vivo bioassays performed on surface water extracts supporting the environmental quality standards (EQS) of the European Water Framework Directive

February 27th, 2018|Comments Off on Effect-based trigger values for in vitro and in vivo bioassays performed on surface water extracts supporting the environmental quality standards (EQS) of the European Water Framework Directive

In ‘Science of the Total Environment 628–629 (2018) 748–765’ a concept for determining effect-based trigger values (EBT) for numerous in vitro bioassays is described. Also for the A-YES® an EBT for estrogenicity is calculated [...]

Validation of Arxula Yeast Estrogen Screen assay for detection of estrogenic activity in water samples: Results of an international interlaboratory study

February 26th, 2018|Comments Off on Validation of Arxula Yeast Estrogen Screen assay for detection of estrogenic activity in water samples: Results of an international interlaboratory study

In the April 2018 issue of Science of The Total Environment the results of the international interlaboratory validation study on the A-YES® test kit acc. to the ISO 19040-2 will be published. Abstract Endocrine-active substances [...]
