Experimental Studies on Epidemic Hepatitis

STUDIES ON HEPATITIS B VACCINES

HBs vaccines were prepared by three different methods: 1) Heat inactivation (Krugman, et.al 1971)2) Ammonium sulphate precipitation followed by column chromatography (Sephadex G-200) 3) PEG-6000 (polyethylene glycol) precipitation followed by column chromatography using Sephadex G-200.
