    Area of Science:

    • Biochemistry
    • Immunology
    • Protein Purification

    Background:

    • Interferon is a crucial cytokine in the immune response.
    • Efficient purification methods are essential for studying interferon's biological functions.
    • Existing purification techniques can be complex and time-consuming.

    Purpose of the Study:

    • To develop a novel solid-phase immunoadsorbent for mouse interferon.
    • To assess the purification efficiency and recovery rate of the immunoadsorbent.

    Main Methods:

    • Preparation of a solid-phase immunoadsorbent targeting mouse interferon.
    • Purification of interferon from crude tissue-culture material using affinity chromatography.
    • Evaluation of recovery rates using different interferon sources (tissue culture, mouse brain, mouse serum).

    Main Results:

    • A single step of affinity chromatography yielded a 1990-fold purification of mouse interferon.
    • High recovery rates (55-103%) were achieved for tissue culture and mouse-brain interferon.
    • A lower recovery (5%) was observed for Sendai virus-induced interferon from mouse serum.

    Conclusions:

    • The developed immunoadsorbent is highly effective for purifying mouse interferon from tissue culture sources.
    • The method offers a significant advancement in simplifying and enhancing interferon purification.
    • Further optimization may be needed for specific interferon types, such as virus-induced interferon from serum.
