Objective: To quantitatively detect hepatitis B virus covalently closed circular DNA (HBV cccDNA) in sera of chronic hepatitis B patients with a newly established assay.
Methods: Primers and probe were designed in highly conservative region of HBV DNA. DNA was extracted from 175 sera samples of chronic hepatitis B patients, and was treated with plasmid-Safe-ATP-dependent Dnase(PSAD) to eliminate the relaxed circular DNA (rcDNA).
