    • Halogen exchange reactions of chloromethyl esters were carried out with excess of sodium iodide (2 equiv) in anhydrous acetonitrile at rt overnight in the dark. After removal of the solvent, the reaction mixture was extracted between water and DCM, the DCM layer was washed with sodium bisulfite solution (5%), followed by brine, and dried over anhydrous sodium sulfate. The organic layer was concentrated to give the iodomethyl esters; also see:

    • 2O (δ 58.6, 58.8 ppm) was recorded and spectra obtained at different time points following the sequential addition of pepsin and DCl as per the SGF composition in Ref. 15 A significant decrease in the peak intensities at δ 58.6, 58.8 ppm was noted after 1 h thereby suggesting decomposition of 1 in SGF.

    • 4, 0.21 mg/ml salmon sperm DNA, and 7% SDS. The radioactive signals were measured using the phosphorimaging method (Optiquant). An image of the radioactive filter was exposed to a Cyclone™ Storage Phosphor Screen (Perkin Elmer Multisensitive Medium, Type MS PPN 7001723). The exposed screen was transferred to the Cyclone™ drum and read using the 600 dpi setting. The data was stored on a computer, and the density of the bands was measured. The ratio of the viral DNA bands to the transgene band was used to determine the concentration of viral DNA per host DNA. This calculation was based upon the knowledge that there were 1.3 copies of the transgene present per host cell with this line of transgenic mice (personal communication to JDM from F. Chisari). The transgene was used as an internal indicator to calculate the pg of HBV DNA per μg of cellular host DNA. The pg HBV DNA/μg host DNA was calculated.
