Technical overview

Somatropin is recombinant human growth hormone: a single-chain 191-amino-acid polypeptide with two disulfide bridges, produced by recombinant expression and described in public reference sources as sequence-identical to pituitary-derived human growth hormone. As a biological substance, identity and quality assessment depends on far more than a nominal purity figure: relevant attributes include primary structure confirmation, higher-order structure, charged and size variants, host-cell protein and host-cell DNA residuals, biological potency in international units, endotoxin, sterility, and container-closure integrity, each defined by a compendial or agreed specification. In most jurisdictions somatropin is a prescription biological product whose manufacture, import and supply require specific authorisation. This record documents identity only. Red Chem Biotech publishes no potency, purity, sterility, or batch documentation for it.

Frequently asked questions

What is somatropin (rhGH)?

Somatropin, CAS 12629-01-5, is recombinant human growth hormone: a 191-amino-acid single-chain polypeptide with two disulfide bridges, produced by recombinant expression. As a biological substance it is prescription controlled in most jurisdictions.

Why is a purity percentage insufficient for a recombinant protein?

Because protein quality is multidimensional. Beyond chromatographic purity, assessment covers primary and higher-order structure, charge and size variants, aggregation, host-cell protein and DNA residuals, biological potency expressed in international units, endotoxin and sterility. A single purity figure without the method and the acceptance criteria conveys very little.
