Product Description
The A-YGS (Arxula-Yeast Glucocorticoid Screen) is an effect-based 96well assay for the detection of hormonal activity of glucocorticoids in various types of water samples. The A-YGS uses the non-conventional and recombinant yeast Arxula adeninivorans as a glucocorticoid responsive biosensor. No sterile conditions are required for the whole test procedure.
Key Characteristics

The A-YGS determines the CEQ (Corticosterone Equivalents) of aqueous samples.

Validation and Standardization

A factorial in-house validation was performed for method validation of the A-YGS.

Test Principle
Genetic Modifications

In the yeast genome the gene for the human glucocorticoid receptor and a reporter gene cassette have been integrated.


Glucocorticoids bind to the receptors and the resulting complexes trigger the transcription of the reporter gene.


The reference standard for calibration and quantification is Corticosterone (CN). The dose-response curve corresponds to a non-linear model.


The detection is performed after reaction of the reporter enzyme phytase with the chromogenic substrate p-nitrophenyl phosphate at 405 nm.
