J.YR 1973 T1 Electrofocusing of Hepatitis B Antigen JF Journal of General Virology, VO 20 IS 2 SP 253 OP 256 DO https://doi.org/10.1099/0022-1317-20-2-253 PB Microbiology Society, SN 1465-2099, AB SUMMARY Hepatitis B (Australia) antigen was isolated from normal serum proteins by gel filtration and electrofocusing. The latter technique revealed a heterogeneity of the small spherical particles associated with hepatitis B antigen activity, there being a variance in determined isoelectric points according to the serological subtype studied. Hepatitis Bantigen isolated in this manner was aggregated by concanavalin A., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-20-2-253
