    Area of Science:

    • Biochemistry
    • Analytical Chemistry

    Background:

    • Isoelectric focusing (IEF) is a powerful protein separation technique.
    • Traditional IEF methods can be time-consuming and may struggle with high-molecular-weight compounds.

    Purpose of the Study:

    • To describe a novel composite gel for isoelectric focusing.
    • To evaluate the gel's performance with high-molecular-weight compounds.

    Main Methods:

    • A composite gel was prepared using 2.5% acrylamide and 0.5% agarose.
    • The gel was utilized for both slab and tube isoelectric focusing.

    Main Results:

    • The composite gel demonstrated enhanced durability compared to conventional gels.
    • Rapid focusing of high-molecular-weight compounds was achieved.

    Conclusions:

    • The acrylamide-agarose composite gel provides a robust and efficient platform for isoelectric focusing.
    • This method is particularly advantageous for the separation of large biomolecules.
