CRISPR/Cas13-assisted hepatitis B virus covalently closed circular DNA detection
17 Mar 2022
Abstract excerpt
BACKGROUND AND AIMS: The formation of an intranuclear pool of covalently closed circular DNA (cccDNA) in the liver is the main cause of persistent hepatitis B virus (HBV) infection. Here, we established highly sensitive and specific methods to detect cccDNA based on CRISPR-Cas13a technology. METHODS: We used plasmid-safe ATP-dependent DNase (PSAD) enzymes and HindIII to digest loose circle rcDNA and...
