How is a solution prepared?
This is how solutions are prepared in the lab.
Step 1 of 8: Disinfect
The stoppers of both vials are wiped with an alcohol swab.
- Disinfect. The stoppers of both vials are wiped with an alcohol swab.
- Draw up. The needle passes through the stopper of the bacteriostatic water and the plunger draws up liquid.
- Transfer. The liquid runs down the inside wall of the vial with powder.
- Mix. The vial is gently swirled until the solution is clear.
- Done. The solution is ready for use in research.
- Take sample. A new needle passes through the stopper and the plunger draws up part of the solution.
- Sample vial. The solution runs through the septum of the screw cap into a sample vial.
- Analyze. The sample vial goes into the autosampler; the instrument measures the solution in vitro.

About Kisspeptin-10
Buy Kisspeptin-10 from PulseChem
A sealed glass vial holds 10 mg of Kisspeptin-10 as a lyophilized (freeze-dried) powder. The label shows the amount and the batch number; that number connects the vial to its certificate of analysis.
PulseChem has Kisspeptin-10 for sale to anyone aged 18 or over who is buying for laboratory research. You can order as a guest or with an account, and you confirm research use at checkout.
Origin of Kisspeptin-10
Kisspeptin-10 consists of the last ten amino acids of kisspeptin-54, which is cut from the protein encoded by the KISS1 gene. UniProt (Q15726) places it at positions 112 to 121 of that 138-amino-acid protein.
In 2001, Kotani and colleagues described peptides of 54, 14 and 13 amino acids from human placenta in the Journal of Biological Chemistry, all with the same amide end, and named them kisspeptins. Kisspeptin-10 is the shortest form in that family. PubChem lists the CAS number 374675-21-5.
Purity and COA for every batch
An external laboratory determines purity by HPLC (≥99%) and identity by mass spectrometry. Kisspeptin-10 ends in an amide; the same chain with a free acid at the end weighs 0.98 g/mol more. The mass measurement has to resolve that small difference. Find the COA by batch number on Lab results.
Storage and shipping
Keep Kisspeptin-10 closed, cool, dry and dark; the label and COA give the conditions. The parcel is shipped from Europe in insulated packaging with tracking, with a cold pack when it is warm. If you order and pay before 3 p.m. Central European time on a working day, it goes out the same day; delivery takes 1–3 working days within Europe. We ship within the EU only.

Kisspeptin-10 is available from PulseChem in this web shop. The 10 mg vial costs €70.45 including VAT, and Kisspeptin-10 is in stock. Orders received and paid before 3 p.m. Central European time on a working day ship the same day; delivery takes 1–3 working days within Europe. Every batch has a COA.
Who can order Kisspeptin-10?
Kisspeptin-10 can be ordered by anyone aged 18 or over who is buying for laboratory research. PulseChem has research peptides for sale to guests and account holders; at checkout you confirm research use. Institutions and companies can also apply for a business account.
How is the purity of Kisspeptin-10 tested?
The purity of Kisspeptin-10 is measured for every batch by an external laboratory using HPLC (≥99%). Mass spectrometry checks identity, including the amide at the end of the chain. You find the COA with both measurements by batch number on Lab results.
Where does Kisspeptin-10 come from?
Kisspeptin-10 is the C-terminal decapeptide of kisspeptin-54, which is cut from the protein encoded by the KISS1 gene; according to UniProt (Q15726), it covers positions 112 to 121 of that protein. Kotani and colleagues described the kisspeptins in 2001 in the Journal of Biological Chemistry. The Kisspeptin-10 sold by PulseChem is made synthetically.
Background from the knowledge base
What does 99% purity mean?
A purity of 99% tells you about the composition of the peptide, not about the amount in the vial. What the number measures, and what it does not.
Why lyophilize?
Peptides are supplied as a freeze-dried powder because they break down quickly in solution. What happens during freeze-drying, and what it means for storage.
