Patent ID: 8192962

Claim:
A process for detecting 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile in a test material, which comprises contacting the test sample with a cell comprising one or more yeast genes selected from the group consisting of YCR107W, YFL056C, YLL057C, YHR139C, YMR004W, YPR167C, YDL218W, YDL243C, YBL075C, YLL056C, YNL277W, YBR008C, YPL280W, YOL165C, YJR155W, YGR142W, YJR010W, YBR241C, YKL107W, YGR154C, YFL030W, YFR030W, YFL055W, YMR322C, YBL065W, YER103W, YBR256C, YGR197C, YLL062C, YDR253C, YJL163C, YLR216C, YNL117W, YLR092W, YBR213W, YPL196W, YHR112C, and YDR374C, and detecting an increase in mRNA, wherein at least a five-fold increase in mRNA of one or more of the genes indicates the presence of 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile in the test material.
