CHAPERONINE-TARGET PROTEIN COMPLEX, METHOD OF PRODUCING THE SAME, METHOD OF STABILIZING TARGET PROTEIN, METHOD OF IMMOBILIZING TARGET PROTEIN, METHOD OF ANALYZING THE STRUCTURE OF TARGET PROTEIN, SUSTAINED-RELEASE PREPARATION AND METHOD OF PRODUCING ANTIBODY AGAINST TARGET PROTEIN

摘要

The present invention provides a chaperonin-target protein complex and a method of producing the same, and a method of stabilizing the target protein, a method of immobilizing the target protein, a method of analyzing the structure of the target protein, a sustained-release formulation, and a method of producing an antibody against the target protein. The chaperonin-target protein complex in the present invention includes a fusion protein having a chaperonin subunit and an affinity tag linked to the chaperonin subunit via a peptide bond and a target protein for which the affinity tag shows a specific affinity, wherein the target protein is bound to the affinity tag by means of the specific affinity, thereby forming a chaperonin ring structure consisting of a plurality of chaperonin subunits. The chaperonin-target protein in the present invention stabilizes the target protein and surely immobilize on a carrier without causing any change in its stereostructure.
