    This study presents a novel electrophoresis method using pore gradient acrylamide gel for high-resolution polypeptide separation. The technique was successfully applied to analyze adenovirus type 2 structural components.

    Area of Science:

    • Biochemistry
    • Molecular Biology
    • Virology

    Background:

    • Polypeptide separation is crucial for understanding protein function and structure.
    • Existing electrophoresis techniques may lack sufficient resolution for complex biological samples.
    • Analysis of viral components requires precise separation methods.

    Purpose of the Study:

    • To introduce and validate a new electrophoresis method for high-resolution polypeptide separation.
    • To assess the applicability of this method for analyzing viral structural proteins.
    • To demonstrate the technique's utility using adenovirus type 2 as a model.

    Main Methods:

    • Electrophoresis using a 15 cm "pore gradient" acrylamide gel.
    • Employing a sodium dodecyl sulfate-urea dissociating system for sample preparation.
