A-YES® test kit for the detection of estrogenic substances
In our uniquely developed A-YES® (Arxula yeast estrogen screen) test method the best properties of all effect-based and not ELISA-related methods are combined. Hence, this test kit enables you to determine the estrogenic activity of aqueous samples already at a concentration of estrogens and estrogenic substances in a single-digit ng/L range.
The robust measurement method is insusceptible to microbial flora and therefore can be applied to complex samples without significant pretreatment (for example, samples from sewage treatment plants or those with high salt content). Sterile conditions are not required. By using standardized production conditions, we can ensure the consistent quality of our test organism. The ready-to-use yeast offers the benefit of significantly reducing your workload. The recombinant test organism Arxula adeninivorans can handle samples that have different salinity and are spiked with endrogenic substances on a single plate within approximately 26 hours.
The A-YES® test kit is suitable for the analysis of
- Ultrapure, drinking and mineral water
- Surface water
- Ground water and well water
- Seawater and brackish water
and for substance testing
The A-YES® test kit is easy-to-use, has a low-detection limit and comes with free analysis software making it ideal for quality control in environmental and food analysis, in addition to various fields of application in biotechnology.
