    This study introduces a novel electrophoresis method using antibody-infused gels to separate specific antigens, such as viruses, from complex mixtures. This technique efficiently isolates target components like hepatitis B antigen from serum.

    Area of Science:

    • Biochemistry
    • Immunology
    • Virology

    Background:

    • Antigen separation is crucial for diagnostics and research.
    • Existing methods may lack specificity or efficiency.
    • Viral and sub-viral particle isolation presents unique challenges.

    Purpose of the Study:

    • To develop a novel method for isolating specific antigens from complex mixtures.
    • To demonstrate the efficacy of antigen separation using electrophoresis and precipitating antibodies.
    • To provide a versatile technique applicable to various biological samples.

    Main Methods:

    • Electrophoresis of antigen mixtures through a gel matrix.
    • Incorporation of precipitating antibodies within the gel, targeting unwanted components.
    • Isolation of the desired antigen by its selective migration and retention.
