Materials and methods

Test guideline
Qualifier:
according to guideline
Guideline:
other: according to P. Sohoni and J.P. Sumpter (1998)
Principles of method if other than guideline:
The aim of the study was to determine the androgenic and antiandrogenic potential of Benzaldehyde, dodecylhydroxy-, oxime, branched (solvent-free and dodecylphenol-depleted). The yeast cells used in the yeast androgen screening (YAS) assay have been stably transformed with genes for the human androgen receptor and the ß-galactosidase reporter gene. Androgenic as weil as antiandrogenic potentials of the test substances mediated by receptor binding or blocking can be determined using this assay, respectively.
GLP compliance:
no
Type of method:
in vitro
