[ABSTRACT] Chronic infection of hepatitis B virus (HBV) is at risk of liver cirrhosis and hepatocellular carcinoma and remains one of the major public health problems worldwide. It is a major barrier of persistence HBV cccDNA under current antiviral therapy as novel strategies of disrupting HBV cccDNA is pressing. The (CRISPR)/Cas9 system is presently emerging in gene editing and we also apply it for targeting and deleting the conserved regions of HBV genome ...
[Enzyme-linked immunosorbent assay (ELISA)] The cell cytotoxicitys of Huh7 and HepG2 after transfection with pCas9 or pX330 for 48 h were analyzed by LDH ELISA kit ( Jianglai, Shanghai, China [1]) for measuring supernanant LDH level. Treatment of 200 ng/mL LPS on Huh7 and HepG2 for 48 h was considered as the positive control. All values (cytotoxicity%) were calculated by the positive control value as the protocol described ...
