Polystyrene is frequently used in resins, and the styrene dimers and trimers eluted from polystyrene have been reported to have estrogenic activity 1.
We have performed a number of in vitro and in vivo tests [i. These results are supported by Fail et al.
In addition, the Japan Environment Agency referred to their studies 9 and removed the styrene dimers and trimers from their list of endocrine disruptors 9. However, Ohyama et al. Recently, several assay systems have been used to assess endocrine-disrupting effects, but a few of these assay systems can cause false-positive reactions when test compounds are at high concentrations To assess the accuracy of the ER binding assay system and the results of Ohyama et al.

Environ Health Perspect — Incubation with the supplied primary and secondary antibodies specifically quantifies the amount of activated transcription factor. Compared to other published data sets, this is the largest and most diverse group of chemicals tested to date using a single assay. Wettstein , Patricia Burkhardt-Holm. The presence of such isoforms has generally been attributed to proteolysis of the native ER [ 43 , 44 ]. In addition, these data are also useful for comparing ER-binding results from a large number of chemicals to small data sets using different assay conditions. Reprod Toxicol —
