Abstract
Rapid and easy preparation of a sample for a gene analysis or high-purity nucleic acid suitable for gene amplification especially, for example, by the PCR method is made possible by a process for treating a paraffin-embedded tissue sample to be used for a gene analysis, which comprises heating an aqueous suspension containing a surfactant having a protein-denaturational action and a deparaffinized tissue sample obtained from a paraffin-embedded tissue sample at 60.degree. C. or higher, or the above-mentioned process which further comprises reacting the heat-treated aqueous solution with a protease, or the above-mentioned process which further comprises reacting the heat-treated aqueous solution with a protease, mixing the resulting reaction solution with a solution containing an organic compound having a protein-denaturational action other than the aforesaid surfactant, and precipitating nucleic acid from the resulting reaction solution by addition of an alcohol.
