Biology-based processes for detecting toxic substances are provided. The processes comprise transforming cells with a vector comprising a polynucleotide which comprises a promoter of certain yeast gene operably linked to a polynucleotide encoding a marker protein; contacting the transformed cells to test sample; and detecting the expression of mRNA encoding the marker protein, thus detecting a toxic compound in the test sample.
提供了基于
生物学的有毒物质检测方法。 这些过程包括用一种载体转化细胞,该载体包含一个多核苷酸,该多核苷酸包括与编码标记蛋白的多核苷酸可操作连接的某些酵母
基因的启动子;将转化细胞与测试样本接触;检测编码标记蛋白的 mRNA 的表达,从而检测测试样本中的有毒化合物。
