Recombinant structural protein production method and analysis method, and protein molded body production method

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a recombinant structural protein having a desired molecular weight, which can obtain the target structural protein with high purity. SOLUTION: The method for producing a recombinant structural protein having a desired molecular weight of the present invention comprises (A) a step of preparing a recombinant structural protein solution in which a recombinant structural protein is dissolved in a solvent for dissolution, and (B) A column in which the recombinant structural protein solution prepared in step (A) is diluted with a mixed solvent containing water, and (C) the recombinant structural protein solution diluted in step (B) is filled with a porous gel. And a step of (D) collecting a fraction containing a recombinant structural protein having a desired molecular weight. [Selection diagram] None
