    Albumin agarose materials show promise for artificial liver support systems, enhancing toxin removal. SepharoseR albumin agarose may offer advantages over Bio--GelR in future hemoperfusion, though modifications are needed for human use.

    Area of Science:

    • Biomaterials science
    • Hepatology
    • Biomedical engineering

    Background:

    • Artificial liver support systems aim to remove toxic substances in patients with liver failure.
    • Albumin-conjugated materials are explored for enhanced binding of protein-bound toxins.
    • Evaluating novel materials for improved hemoperfusion efficacy is crucial.

    Purpose of the Study:

    • To investigate the physical, adsorptive, and flow properties of two albumin-conjugated agarose materials.
    • To assess their potential for use in artificial liver support systems.
    • To compare SepharoseR albumin agarose with Bio--GelR albumin agarose for hemoperfusion.

    Main Methods:

    • In vitro investigation of physical, adsorptive, and flow properties.
    • Binding experiments with chenodeoxycholic acid and unconjugated bilirubin.

  • Flow experiments using blood and saline.

    • Main Results:

    • Both albumin agarose materials exhibited relevant properties for artificial liver support.
    • SepharoseR albumin agarose showed potential advantages over Bio--GelR albumin agarose in binding and flow characteristics.
    • Binding affinities for target toxins were observed, suggesting enhanced removal capabilities.

    Conclusions:

    • Albumin-conjugated agarose materials, particularly SepharoseR, show potential for enhancing toxic protein-bound substance removal in artificial liver support.
    • Further modifications are necessary to optimize SepharoseR albumin agarose for clinical scale-up and human application in hemoperfusion systems.
    • These findings suggest a promising direction for developing more effective hemoperfusion therapies.
