The present invention provides a stable and bioactive recombinant small-loop modified somatotropin which has its small-loop cysteines changed to other amino acids or deleted altogether and a method for producing such a small-loop modified somatotropin. Also provided by the present invention are DNA sequences coding for such small-loop modified somatotropins, plasmids containing such sequences, and organisms containing such plasmids. Furthermore, pharmaceutical compositions including small-loop modified somatotropins and methods for using such pharmaceutical compositions are disclosed.

Stable and bioactive modified porcine somatotropin and pharmaceutical

Human Growth Hormone-Releasing Factor (hGRF) analogs having the sequence [Pro.sup.0, X.sup.15, Y.sup.27 ]-hGRF(1-A)-B, wherein X is selected from the group consisting of Ala and Gly, Y is selected from the group consisting of Ile, Leu, Val, Nle and Met, A has a value from 29-44, and B is NH.sub.2, OH or COOH are synthesized and administered to animals to stimulate the release of Growth Hormone (GH).

An improved process is described for recovering proteins from insoluble inclusion bodies produced in transformant microorganisms. Sidestream precipitates isolated from chromatography effluent are resolubilized in a denaturing agent and the resolubilized proteins are renatured either by direct dialysis into denaturant-free buffer or by dialysis into a weaker denaturing agent followed by dialysis into denaturant-free buffer.
