Introduction of a QM system according to ISO 9001

April 16th, 2019|Comments Off on Introduction of a QM system according to ISO 9001

We have made it our task to introduce and establish a quality management system in order to be certified according to well accepted standard ISO 9001:2015 for our products and services. With this project [...]

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 [...]

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 [...]
