Abstract: The present inventors have found that by cultivating insect cells, into which the Cas3 gene has been introduced, at relatively low temperatures, it is possible to efficiently express recombinant Cas3 proteins with maintained activity, and by purifying the soluble fractions of these cells, it is possible to collect active forms of the recombinant Cas3 proteins in high purity and high yield.

Abstract: It has been found that by mixing a single-stranded probe DNA whose cleavage can be detected in a reaction system containing a CRISPR-Cas3 system and a sample from which to detect a target DNA, it is possible to detect the target DNA in the sample by using, as indication, a signal generated by the cleavage of the single-stranded probe DNA.
