In our uniquely developed A-YAS® (Arxula Yeast Androgen 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 androgens and androgenic substances in 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. Using standardized production conditions, we can ensure the consistent quality 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 androgenic substances on a single plate within approximately 26 hours.
The A-YAS® Test-Kit is suitable for the analysis of
