  • Method of producing insulin-like growth factor-I (IGF-I) and insulin-like growth factor binding protein-3 (IGFBP-3) with correct folding and disulfide bonding
    Patent number: 5789547
    Abstract: The present invention provides a novel method for refolding insulin-like growth factor I (IGF-I) and insulin-like growth factor binding protein 3(IGFBP-3). The method involves mixing of IGF-I and IGFBP-3 together in a cofolding reaction. The inventive cofolding method results in substantially higher yields of correctly folded protein for both molecules and alters the kinetics of refolding. The method includes the production of correctly folded IGF-I, IGFBP-3, and/or IGF-I/IGFBP-3 complex.
