Sermorelin
Price range: $60.00 through $105.00
GHRH analog studied in growth-hormone research.
Description
GHRH analog studied in growth-hormone research. Supplied strictly for laboratory and in-vitro research use — not for human or veterinary consumption.
Sermorelin is the first 29 residues of human growth-hormone-releasing hormone, made as a C-terminal amide. It is an unmodified natural sequence, with no substituted or acylated residues, which is what separates it from the modified GRF analogues also listed here.
| Compound | Sermorelin (GRF 1-29 amide) |
|---|---|
| Also known as | GRF(1-29)NH2, growth-hormone-releasing factor (1-29) |
| Class | Synthetic 29-residue peptide |
| Structure | H-Tyr-Ala-Asp-Ala-Ile-Phe-Thr-Asn-Ser-Tyr-Arg-Lys-Val-Leu-Gly-Gln-Leu-Ser-Ala-Arg-Lys-Leu-Leu-Gln-Asp-Ile-Met-Ser-Arg-NH2. C-terminally amidated. |
| Molecular formula | C149H246N44O42S |
| Molecular weight | 3357.9 g/mol (free peptide) |
| CAS number | 86168-78-7 (free peptide). Sermorelin acetate is separately registered as 114466-38-5. |
| Appearance | White to off-white lyophilised powder. |
| Purity specification | ≥98% by HPLC |
Every lot ships against its own certificate of analysis. Search by lot number on the certificates of analysis page, or check the paperwork before you order.
Sermorelin is supplied for laboratory research use only. It is not a drug, food or cosmetic, and it is not for human or veterinary use.
| Reconstitution | Bacteriostatic water or sterile water. Dissolves more readily if the diluent is added down the vial wall and the vial is left to stand rather than agitated. |
|---|---|
| Storage, lyophilised | -20 °C, sealed and desiccated, protected from light. |
| Storage, reconstituted | 2-8 °C, protected from light. Use within 2-4 weeks, or freeze single-use aliquots at -20 °C for longer holds. |
| Shipping | Shipped at ambient temperature. Lyophilised material tolerates transit without a cold chain; move it to the freezer on arrival. |
Working notes
- Let a vial come to room temperature before opening it. Opening a cold vial draws in moist air, and lyophilised powder takes up water quickly.
- Add the diluent slowly down the inside wall of the vial rather than directly onto the powder cake, and let it dissolve on its own. Shaking a peptide solution is the fastest way to denature it.
- Wipe the stopper with alcohol before every draw, and keep solutions out of direct light.
- Repeated freeze-thaw cycles cost you more purity than time in the fridge does. If a vial will be used over weeks, aliquot it once and freeze the aliquots.
