Sermorelin is a synthetic GHRH (1-29) fragment, the shortest sequence that retains full GHRH activity. It is used in pituitary somatotroph culture to study cAMP accumulation and growth hormone release, and NuVion stocks it in Australia as a 5mg lyophilised vial.
- Synthetic GHRH (1-29) fragment, the shortest fully active GHRH sequence
- Used in pituitary somatotroph culture models
- Applied in cAMP accumulation and growth hormone release assays
- Supplied lyophilised, purity by RP-HPLC and identity by mass spectrometry
Sermorelin structure and research use
Sermorelin is the first 29 amino acids of human growth hormone-releasing hormone, with an amide group at the C-terminus. That is the shortest stretch of the 44 amino acid hormone that keeps full activity at the GHRH receptor. In the laboratory it is used in pituitary somatotroph culture for work on cAMP accumulation and growth hormone release.
Sermorelin research applications
- CRE-luciferase reporter assays in HEK293 or CHO cells expressing recombinant GHRHR, for EC50 determination
- Radioligand displacement on GHRHR-expressing membranes, giving Ki values for new analogues and antagonists
- Calcium imaging with Fura-2 or Fluo-4 in somatotroph-enriched cultures to resolve the calcium-entry phase
- LC-MS after incubation with purified DPP-IV, quantifying GRF(3-29), sulfoxide and deamidated species
