Abstract
A method of assaying the efficacy and/or toxicity of a test substance by expression of a specific gene in a cell or a microorganism, which comprises treating the cell or the microorganism with the test substance, a step of amplifying an RNA having a sequence homologous or complementary to a specific sequence in a target RNA obtained as the result of transcription of the specific gene, and a step of determining whether the target RNA is transcribed through the expression of the specific gene by detecting the RNA amplified in the previous amplification step.
