31,278-00 STABILIZATION OF SOMATOTROPINS AND OTHER PROTEINS BY MODIFICATION OF CYSTEINE RESIDUES ABSTRACT OF THE INVENTION The present invention relates to physiologically-active derivatized natural and recombinant mammalian and human proteins and polypeptides. The invention provides chemical methods for derivatizing natural and recombinantly-derived proteins or polypeptides containing cysteine residues, either naturally or through site specific mutageneses. The pharmaceutical compositions containing said derivatized proteins and/or polypeptides are formulated to provide stable, long-acting compositions of such proteins and/or polypeptides, previously difficult to achieve.
