Product Description
The A-YESlumi (Arxula-Yeast Estrogen Screen) with luminescence detection is an effect-based 96well assay for the fast and sensitive determination of the estrogenic activity in various types of aqueous samples. The A-YESlumi uses the non-conventional and recombinant yeast Arxula adeninivorans as an estrogen responsive biosensor. No sterile conditions are required for the whole test procedure.
Key Characteristics

The A-YESlumi determines the EEQ (17β-Estradiol Equivalents) in aqueous samples with minimal requirement of sample volume. The assay has a superior sensitivity and can be used as a fast-screening test prior to chemical analysis.

Validation and Standardization

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

Test Principle
Genetic Modifications

In the yeast genome the gene for the human estrogen receptor (hERα) and a reporter gene cassette have been integrated.


The detection of light is performed after reaction of the reporter enzyme luciferase with the substrate luciferin.


Estrogens and estrogen-like substances bind to the receptors and the resulting complexes trigger the transcription of the reporter gene.


The reference standard for calibration and quantification is 17β-Estradiol (E2). The dose-response curve corresponds to a non-linear model.
