A METHOD FOR PRODUCTION OF ANTISERA TO HEPATITIS B ANTIGEN SUBTYPES, AND THE DISTRIBUTION OF SUBTYPES D AND Y AMONG NORWEGIAN HEPATITIS B PATIENTS
Abstract
A method for production of antisera to hepatitis B antigen (HBsAg) subtypes D and Y is described. The method is based on the coupling of HBsAg to a colloidal silica gel (Aerosil), and the selective adsorption of unwanted antibodies from antisera with this preparation. Some results obtained with Norwegian hepatitis patient sera are included.
