Um for 1 h, and fixed with 4 paraformaldehyde at room temperature for 20 min. The cells were then washed three times with PBS and blocked with 2 BSA for 30 min. The FITC-conjugated synthetic VP2 peptides were incubated with the cells for 1 h at 37uC. After three washes, DAPI was used to stain the nucleus, and the slides were observed using fluorescence microscopy. Unrelated peptides labeled with FITC were used as negative controls. The binding ability of synthetic VP2 peptide was further verified by flow cytometry using a POR 8 procedure similar to the one described above, except that VIP was not added to these cells. Finally, the cells were resuspended in 300 ml of PBS for flow cytometry analysis.Supporting InformationDataset S1 Original full DNA sequences of the selected phage clones. After the fourth round of panning, 60 phage clones were randomly selected, amplified and purified. ssDNA was extracted and DNA sequencing was performed using the -96gIII primer. The original full DNA sequences of the selected phage clones were shown in this dataset.

Statistical analysis of the data was performed using SPSS 17.0 (SPSS, Chicago, IL, USA). Statistical significance was determined using Student’s t-test. The Wilcoxon signed rank test was employed for non-parametric analysis. A value of p,0.01 was considered statistically significant.Author ContributionsConceived and designed the experiments: QL BT.

There are approximately 400 million people worldwide who are chronically 1655472 infected with hepatitis B virus (HBV), of whom 75 live in the Asia-Pacific region. Chronic hepatitis B results in liver disease progressing to cirrhosis and hepatocellular carcinoma (HCC) and is responsible for approximately one million liverrelated deaths per annum [1]. Treatment of HBV involves finite administration of pegylated or unpegylated interferon alfa, or indefinite administration of anti-HBV nucleoside/nucleotide analogues. Five such analogues are currently available. Lamivudine, a deoxycytidine analogue, was the first nucleoside approved for use in HBV and lamivudine monotherapy remains common despite high rates of treatment-emergent drug resistance [2]. Entecavir is a deoxyguanosine analogue with a high genetic barrier to resistance in treatment-naive patients [3]. However, lamivudine resistance predisposes HBV to subsequent entecavir resistance [4]. Telbivudine is an L-deoxythymidine analogue with superior MedChemExpress Biotin-NHS efficacy to lamivudine [5] but a similar resistance profile [6]. Finally, the nucleotides adefovir and tenofovir are both acyclic mimetics of deoxyadenosine monophosphate which retain activity against lamivudine- and telbivudine-resistant HBV [6]. However, adefovir is associated with dose-dependent nephrotoxicity which restricts its dosing to 10 mg daily [7], at which dose it demonstrates inferior virologic efficac.Um for 1 h, and fixed with 4 paraformaldehyde at room temperature for 20 min.
