The kit comprises a crDNA amplification primer pair, a Cas12a protein, a DNA polymerase for variable temperature amplification, an RNA polymerase, and a single-stranded DNA reporter molecule. The crDNA amplification primer pair comprises a promoter sequence for amplifying a transcriptional template capable of carrying out in vitro transcription to generate crRNA. The crRNA comprises an anchor sequence for binding to the Cas12a protein and a guide sequence for targeting a target sequence. The length of the guide sequence is 43 bp-75 bp. The described kit does not need to additionally provide RNA, which is beneficial to the storage and transportation of the kit. The kit can be used for POCT detection, is suitable for rapid and highly sensitive on-site screening of various viruses, can suppress the spread of the viruses to the maximum extent, and has a wide application prospect.
