STABLE BIOTINYLATED BIOMOLECULE COMPOSITION AND METHODS

摘要

Compositions and methods for biotinylated biomolecules, such as enzymes, are disclosed. The compositions include a biotinylated biomolecule, a biomolecule protectant, a buffer, a bulking agent selected from one or more water soluble, nonionic polymers and preferably a terminal sterilization protectant. The compositions can be utilized either as aqueous solutions or preferably in dried form, e.g., as a lyophilized powder cake. They have applicability in any case wherein avidin/biotin technology is used, and are particularly important as compositions containing a thrombin-like enzyme. The preparation of a fibrin monomer and fibrin monomer-based fibrin sealants are an example wherein avidin/biotin technology is used and methods of providing such monomers are also disclosed.
