  • Stable bioactive somatotropins
    Patent number: 5079230
    Abstract: The present invention provides a stable and bioactive somatotropin which has its small-loop sulfhydryl groups derivatized and a method for producing the small-loop derivatized somatotropin. The small-loop derivatized somatotoropin is stable during long term storage, i.e. it forms very few dimers, oligomers, and aggregates which inactivate the somatotropin, and has a bioactivity equal to or greater than that of the non-derivatized somatotropin.
