Humatrope

Humatrope (somatotropin) is a polypeptide hormone of rDNA origin. Manufactured by Eli Lilly and Company, it is used to stimulate linear growth in pediatric patients who lack adequate normal human growth hormone. It has 191 amino acid residues and a molecular weight of 22,125 daltons.

Its amino acid sequence is identical to that of human growth hormone of pituitary origin (anterior lobe). Humatrope is synthesized in a strain of E. coli modified by the addition of a gene for human growth hormone.
