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

The A-YPS determines the PEQ (Progesterone Equivalents) of water samples with high matrix load.

Validation and Standardization

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

Test Principle
Genetic Modifications

In the yeast genome the gene for human progesterone receptor β (hPRβ) and a reporter gene cassette have been integrated.


Progestogens and progestogenically active substances bind to the receptors and the resulting complexes trigger the transcription of the reporter gene.


The reference standard for calibration and quantification is Progesterone. The dose-response curve corresponds to a non-linear model.


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