A-YASHT for the detection of androgenic effects

The biological test system A-YASHT (Arxula-Yeast Androgen Screen for High Throughput-applications) is based on the use of androgen sensitive yeast, Arxula adeninivorans. The test was developed for parallel screening of large sample sizes, utilizing ready-to-use 384-well test plates and an optimized fluorescence reporter based on dsRED. The test can therefore be used in combination with automated liquid handling systems.

A-YASHT contains the growth medium and yeast mixed and lyophilized in every well. Only 40 µl of sample has to be added to each well. After 18 to 20 hours of incubation, the fluorescence (excitation 535 nm, emission 595 nm) can be measured directly. On request we offer individual configuration of the 384-well test plates for analyzing special test controls e. g. blanks (wells without yeast).

A-YASHT can be used for:

  • Determination of potential androgenic effects of drug candidates and new chemicals

  • Semi-quantitative analysis of ultrapure-, drinking- and mineral water

  • Semi-quantitative analysis of ground-, well- and surface water with low matrix effects

The test is not suitable for samples with high matrix load e. g. wastewater samples.

Response (Relative Fluorescence Units, RFU) of various androgens and androgen active substances analyzed with the A-YASHT.
