Abstract
The present invention provides a bioassay system, for detection of hazardous chemical substances, natural toxic substances in the environment and unknown toxic compounds, with high sensitivity, simplicity and speed. The invention provides cells and a method of using the cells for use in the bioassay system. The cell provided by the invention contains a heat shock factor binding DNA sequence and a transcriptional regulatory sequence necessary on an occasion of stress induction as a transcriptional regulatory factor binding site. The cell also possesses a reporter gene under the control of the promoter. The reporter gene is connected, on the downstream side, to the SV40pA signal without any intervening intron.
