摘要：The NH2-terminal 134 amino-acid fragment of the reduced-carbamidomethylated human somatropin molecule is found to react noncovalently with the COOH-terminal 51 amino-acid fragment in solutions of pH 8.4 at 2 degrees to restore full biological activity as evidenced by the rat tibia and pigeon crop-sac assays. In addition, circular dichroism spectra of the recombinant show the conformation to be completely repaired in comparison with that of the native hormone.
