title: [Isoelectric spectra of hepatitis B antigen antibodies to it].
abstract: Isoelectric focussing in a stable pH-gradient of ampholines, serum and fraction 4-4, containing hepatitis B antigen demonstrated that the antigen occupied the pI 4.31--6.03 zone with the maximum activity at pI 4.31--5.56. The activity of antibodies to the hepatitis B antigen was revealed in a donor serum and in the gamma-globulin fraction in the pI 7.76--8.4 zone with the activity maximum at pI 8.03--8.23. It was demonstrated immunochemically that antibodies against hepatitis B antigen belonged to immunoglobulin G.
