Description
Kisspeptin studied in reproductive-endocrine research. Supplied strictly for laboratory and in-vitro research use — not for human or veterinary consumption.
Kisspeptin-10 is the C-terminal decapeptide of kisspeptin-54. The three names in circulation - KP-10, kisspeptin 112-121 and metastin 45-54 - all refer to the same molecule; they differ only in which precursor is being numbered. The rodent sequence is genuinely different and carries its own CAS, so species matters on this one.
| Compound | Kisspeptin-10 (human) |
|---|---|

| 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.
Kisspeptin-10 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 | Readily soluble in water; bacteriostatic water or sterile water. |
|---|---|
| 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.
