The A-YES is a robust assay for analyzing EEQ (17β-Estradiol Equivalents) and LID (Lowest Ineffective Dilution) of samples especially with high matrix load or with high salt content. No sterile conditions are required for the whole test procedure.
The A-YES is a standardized method according to ISO 19040-2:2018. An international interlaboratory trial was performed for method validation.

Will this test fits to my purposes? We give sufficient support for choosing the right test for your application as well as before and during test establishment and for data evaluation.
In the yeast genome the gene for the human estrogen receptor (hERα) and a reporter gene cassette have been integrated.
Estrogens and estrogenically 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 17β-Estradiol (E2). 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.
