Somatropin (GH)

Somatropin (recombinant human growth hormone, 191 aa)

Somatropin is recombinant human growth hormone, a 191-amino-acid protein produced in E. coli that is structurally identical to the growth hormone the pituitary gland makes naturally. It has been commercially available since 1985 and is an approved medicine for several growth-hormone deficiency conditions. In research it is the reference standard for the entire growth-hormone field.
