由于雌激素类物质化学结构的多变性，只有通过生物试验提供的相关活性测定，才能对环境样品的雌激素类作用做出适当定性分析。为此，作者建立了一种快速、通用的酵母报告基因雌激素试验（ＹＥＳ）。该法可用于任何可溶于二甲亚砜的样品，２ｈ完成测定。迄今我们采用了酵母菌株 Due to the variability of the chemical structure of estrogens, only the qualitative analysis of the estrogenic effects of environmental samples can be made only by the relevant activity measurements provided by biological tests. To this end, the authors established a rapid and versatile yeast reporter test for estrogen (YES). The method can be used for any dimethyl sulfoxide-soluble samples, 2h to complete the determination. So far we have used yeast strains
