Abstract

Compositions and methods for avidin immobilized on an inert support material, e.g., agarose, are disclosed. The compositions have high activity levels of avidin and may further include a bulking agent, e.g., maltose, and a protectant to maintain the stability and integrity of the avidin agarose during lyophilization and terminal sterilization processes. A dry composition, and wet compositions such as a gel, slurry or suspension having avidin immobilized on an inert support material are disclosed. The dry composition has at least 1000 biotin binding units of activity, and the wet compositions have at least 50 units of binding activity. These compositions have applicability in any instance where avidin agarose and/or the avidin/biotin technology are useful. In particular, the present compositions are useful in an enzyme capture system to prepare fibrin monomer useful for fibrin sealants.
