title: Chemical synthesis of insulin-like growth factor II.
abstract: Human insulin-like growth factor II (IGF-II) with 67 amino acids and three disulfide bridges has been synthesized by the solid-phase method. The synthetic hormone is shown to be homogeneous in high performance liquid chromatography (HPLC), high performance partition chromatography (HPPC), and chromatofocusing. It is indistinguishable from natural hormone in HPLC, peptide map of thermolysin digests, amino acid composition and radioreceptor binding assay. Thus, synthetic and natural IGF-II are identical.
