  • Antibody-specific solid phase immunoadsorbent, preparation thereof, and antibody purification therewith
    Patent number: 4264449
    Abstract: An antibody-specific solid phase immunoadsorbent is prepared by adsorptively binding a lipid-containing viral antigen, such as hepatitis B surface antigen, to the surface of a porous glass carrier having an average pore diameter within the range of about 40-200 nm and an adsorptive surface which within the pH range of 2-8 is capable of selectively and stably binding lipid-containing materials, employing an adsorption buffer having a pH within such range. The high adsorptive selectivity of the carrier surface for the antigen under such conditions, enables preparation of the immunoadsorbent directly from whole human plasma containing the antigen, without the necessity for prior antigen purification.
    Type: Grant
