    摘要: A method of purifying a protein is disclosed which entails: a) fusing a site-specific affinity-tagged cysteine protease domain to a target protein to form a tagged fusion protein; b) activating the site-specific cysteine protease domain of the tagged fusion protein by subjecting the site-specific affinity-tagged cysteine protease domain to an inducer, which induces autoprocessing at a cleavage site; thereby releasing untagged target protein; and c) isolating the untagged target protein.
