Kisspeptin-10 at a glance

What is Kisspeptin-10?

Kisspeptin-10 is a Decapeptide – that is, a peptide chain consisting of ten amino acids. It is the C-terminal fragment of the KISS1 gene product, also referred to as metastin; it also appears in the literature under the synonyms metastin fragment and kisspeptin-112-121. It is supplied as a stable lyophilised product in a sealed vial (10 mg). In laboratory research, Kisspeptin-10 serves as a well-defined reference substance because it represents the short, active C-terminus of the kisspeptin family. The CAS number (374675-21-5) and molecular formula (C₆₃H₈₃N₁₇O₁₄) are documented in the batch-specific certificate of analysis.

Molecular profile & target structure

Kisspeptin-10 is derived from the larger precursor metastin (the KISS1 gene product) and corresponds to its C-terminal ten amino acids. This conserved C-terminus is the region described in the literature as crucial for recognition by the receptor GPR54 – also KISS1R referred to as – described. Due to its manageable length, defined sequence, and good analytical characterisation, kisspeptin-10 is frequently used as a reference in biochemical and neuroendocrine study models. The combination of a clearly delineated structure and a defined target system makes the decapeptide an established tool in receptor and axis-related research approaches.

What in-vitro and animal model studies document

The following summary reflects only what is described in the publicly accessible preclinical literature – it is not a statement about an effect or suitability in humans.

• GPR54/KISS1R binding models: Published in vitro studies examine kisspeptin-10 in receptor binding models at the GPR54 (KISS1R) receptor.
• Neuroendocrine GnRH axis: Several animal model studies document observations of kisspeptin-10 in neuroendocrine models of the GnRH axis.
• Peptide-receptor interaction: Kisspeptin-10 is used as a model peptide for characterising the interaction between the C-terminal KISS1 fragment and its target receptor.

These observations stem from in-vitro and animal models. They establish research interest in kisspeptin-10, but do not make any statements about safety, efficacy, or application outside of laboratory research.

Purity, COA & Analytical Testing

Purity and identity are the two values that count. HPLC demonstrates purity (target value ≥ 99 %), LC-MS confirms the identity via molecular mass. Both values are listed on the batch-related COA. We explain how to read such a certificate in Understanding and reading a Certificate of Analysis (COA); the procedures themselves in Peptide Purity: HPLC and LC-MS Explained.

Storage & Handling

As a lyophilisate, Kisspeptin-10 is stable when stored is kept cool, dry and protected from light and stored – ideally at -20°C for longer storage. Please refer to the COA for batch-specific information. Principles: Storing and Handling Research Peptides.

Buying Kisspeptin-10 in the EU – what matters

What matters is not the price, but this: Does the label match the contents? Here's what BlitzLab delivers on:

• Batch-specific COA from a third-party laboratory – HPLC (purity) and LC-MS (identity), carried out externally, not by us.
• EU Shipping, discreetly packaged, with tracking – usually 2–5 working days.
• Transparent RUO stance – clear labelling, complete Compliance page, no claims of efficacy or cure.
