Abstract: Provided is a kit for rapid detection of avian leukosis virus subgroup J (ALV-J) based on a CRISPR/Cas13a system. The method is based on the combination of the CRISPR/Cas13a system and recombinase aided amplification (RAA) for ALV-J detection. An oligonucleotide probe is designed as a substrate for CRISPR/Cas13a trans-cleavage and produces a detectable signal. The method can substantially improve detection sensitivity by amplifying a detection signal twice by RAA and T7 transcription. The detection method further exhibits excellent specificity, allowing for clear differentiate from other avian viruses. It does not require expensive experimental equipment and special laboratory environment, and it is rapid and efficient. The method is of great significance for biological research and on-site detection of ALV-J.
