    Area of Science:

    • Biochemistry
    • Chromatography
    • Protein Purification

    Background:

    • Affinity chromatography is a powerful technique for protein purification.
    • Lectins, particularly Concanavalin A (Con A), are useful for targeting glycoproteins.
    • Immobilization of lectins onto matrices is crucial for column preparation.

    Purpose of the Study:

    • To describe a protocol for preparing lectin affinity chromatography columns.
    • To provide a general method for purifying glycoproteins using immobilized Con A.
    • To detail methods for immobilizing Con A on various preactivated matrices.

    Main Methods:

    • Preparation of lectin affinity chromatography columns.
    • Immobilization of purified lectins onto preactivated matrices.
    • Purification of glycoproteins using immobilized Concanavalin A (Con A).

    Main Results:

    • A protocol for lectin affinity chromatography column preparation was established.
    • Methods for immobilizing Con A on CDI agarose, Affi-Gel 15, and carbonyldiimidazole-activated agarose were successfully applied.
    • A general method for glycoprotein purification using immobilized Con A was demonstrated.

    Conclusions:

    • The described protocol enables the efficient preparation of lectin affinity chromatography columns.
    • Immobilized Con A is effective for the purification of glycoproteins.
    • The methods provide flexibility in choosing matrices for lectin immobilization.
