Insulin-like Growth Factor-binding Protein 1, Recombinant, Rat, aa26-272 (Igfbp1)

IGF-binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth promoting effects of the IGFs on cell culture. They alter the interaction of IGFs with their cell surface receptors. Promotes cell migration. Source: Recombinant protein corresponding to aa26-272 from rat insulin-like growth factor-binding protein 1, expressed in E. coli.
