ABSTRACT:
Hepatitis associated antigen (HAA) in human blood serum is precipitated on HAA-specific antibodies immobilized on the inner wall of a plastic tube. A solution of HAA-specific antibodies tagged with fluorescein is held in contact with the deposited antigens until a portion of the antibodies from the solution is affixed to the antigens. The residual, tagged antibodies in the solution are exposed to a light pulse, and the resulting fluorescence is measured as an inverse indication of HAA in the blood serum.
