title: Detection of hepatitis B antigen by counter-immunoelectrophoresis: enhancing role of homologous serum diluents.
abstract: Dilution of hyperimmune hepatitis type B antibody in undiluted homologous species normal serum has resulted in enhanced sensitivity for detecting hepatitis B antigen by a discontinuous counter-immunoelectrophoresis method compared to hepatitis type B antibody diluted in heterologous species normal serum or buffer solutions.
