    Summary

    New enzyme immunoassay sheets for alpha-fetoprotein detection were developed using radiation polymerization. Optimal conditions, including low monomer and antibody concentrations, yielded highly sensitive alpha-fetoprotein measurement sheets.

    Area of Science:

    • Biochemistry
    • Materials Science
    • Analytical Chemistry

    Background:

    • Alpha-fetoprotein (AFP) is a biomarker for liver cancer and other conditions.
    • Accurate and sensitive detection of AFP is crucial for early diagnosis and monitoring.
    • Existing immunoassay methods may require optimization for improved performance.

    Purpose of the Study:

    • To develop and characterize immobilized anti-alpha-fetoprotein sheets for enzyme immunoassay.
    • To investigate the impact of preparation conditions on the activity and sensitivity of these sheets.
    • To assess the applicability of the developed sheets for sensitive AFP detection.

    Main Methods:

    • Preparation of immobilized anti-alpha-fetoprotein sheets via radiation polymerization of hydrophilic monomers.
    • Systematic study of the relationship between preparation parameters and sheet activity.
    • Evaluation of factors including monomer concentration, polymer hydrophilicity, coating volume, and antibody concentration.
    • Assessment of sheet performance in enzyme immunoassay for AFP detection.

    Main Results:

    • Sheet activity was significantly influenced by monomer concentration, polymer matrix hydrophilicity, coating volume, and antibody concentration.
    • Optimal sheet activity was achieved at relatively low monomer and antibody concentrations.
    • The developed immobilized sheets demonstrated high sensitivity for AFP detection.
    • The sheets proved applicable for enzyme immunoassay of alpha-fetoprotein.

    Conclusions:

    • Radiation polymerization offers a viable method for preparing active immobilized anti-AFP sheets.
    • Careful optimization of preparation conditions, particularly monomer and antibody concentrations, is key to maximizing assay sensitivity.
    • These novel sheets represent a promising tool for sensitive and effective enzyme immunoassay of alpha-fetoprotein.
