Jintropin, commonly known as recombinant human growth hormone for injection, is a white freeze-dried powder mainly composed of recombinant human growth hormone and a shaping agent.

Molecular formula: C990H1528N262O300S7, a protein composed of 191 amino acids.

Molecular weight: 22125D

Active ingredient source: This product is recombinant human growth hormone (rhGH) produced through gene recombinant Escherichia coli secretory expression technology. Its precursor is synthesized in an Escherichia coli strain containing the human growth hormone gene, and secreted into the parietal space through signal peptide traction. The signal peptide is cleaved, and the peptide molecules are correctly folded into active growth hormone molecules. This product contains 191 amino acid residues with a molecular weight of 22125 Daltons. Its amino acid content, spatial conformation, and sequence are identical to those of human growth hormone.

·Used for children with slow growth caused by endogenous growth hormone deficiency;

·Used for the treatment of severe burns;

·Used for growth hormone deficiency caused by clear hypothalamic pituitary diseases and significant growth hormone deficiency confirmed by two different growth hormone stimulation tests.
