Somatropin HGH 36 IU

Somatropin HGH 36 IU — the full recombinant growth hormone molecule
Not a fragment, not an analogue, not a secretagogue. Somatropin is the complete 191-amino-acid human growth hormone sequence, produced recombinantly and standardised by biological activity.

What is Somatropin?

Somatropin is recombinant human growth hormone: a 191 amino acid single-chain polypeptide with two disulphide bridges, identical in sequence to the pituitary-derived hormone. Its three-dimensional four-helix-bundle fold is essential to activity, since the growth hormone receptor is engaged through a two-step dimerisation mechanism that depends on two distinct binding surfaces. In research it serves as the definitive reference standard against which secretagogues, GHRH analogues and GH fragments are benchmarked — the full molecule against which partial tools are measured.

Research interest

• GH receptor dimerisation — studied as the canonical ligand in research on receptor activation and JAK-STAT signal transduction.
• IGF-1 axis regulation — investigated in research contexts examining downstream hepatic IGF-1 expression.
• Metabolic and growth pathways — of interest to researchers exploring protein, lipid and carbohydrate handling in preclinical systems.
• Reference standardisation — used as the comparator against which GH secretagogues and fragments are benchmarked.
• Recombinant protein science — a foundational case study in the production and characterisation of a folded therapeutic-class protein.

Somatropin is a full folded protein, not a short peptide, and its handling demands reflect that. Denaturation through heat, agitation or freeze-thaw destroys receptor-binding capability without necessarily altering mass spectrometry results, which is why sourcing and cold-chain integrity matter as much as the certificate.

Specifications

• Storage: 2-8 °C sealed; protect from freezing once in solution

Handling & storage

Store sealed lyophilised vials at -20 °C for long-term stability; short periods at 2-8 °C are generally tolerated during transit and handling. Keep vials sealed, protected from light and away from moisture and repeated temperature swings. Handle as a folded recombinant protein. Keep the sealed vial refrigerated and protected from light; avoid vigorous shaking at every stage, as mechanical agitation denatures the four-helix structure. Reconstitution should be performed gently per the laboratory's validated procedure, directing diluent down the vial wall, and the solution kept cold and used within the facility's stability window.

Why researchers buy from Rogue

• Batch-tested, not batch-guessed — purity and identity verified before a vial is ever listed.
• Authentic European sourcing — a short, controlled supply chain with sealed, tamper-evident vials.
• Consistency across orders — lot-to-lot control so repeat work stays comparable.
• Fast, tracked, discreet — quick EU-wide dispatch in unmarked packaging.
