Synthetic decapeptide amide, YNWNSFGLRF-NH₂, also catalogued as metastin (45–54). Planned as a 5 mg listing to the same standard as the rest of the catalogue: lyophilised powder in a crimp-sealed glass vial, held in UK stock, dispatched tracked on working days with UK delivery included in the price.
Kisspeptin-10 is a synthetic decapeptide: ten amino acid residues with the sequence YNWNSFGLRF (Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe), amidated at the C-terminus. The sequence is the C-terminal ten residues of the 54-residue peptide kisspeptin-54, also called metastin, which is why the material is catalogued in the literature as metastin (45–54); what we plan to list is made by chemical synthesis and is not that longer peptide. Its identifiers are CAS 374675-21-5, molecular formula C63H83N17O14 and a molar mass of approximately 1302.5 g/mol for the free peptide.
The planned listing is 5 mg fill weight as lyophilised powder in a crimp-sealed glass vial. Fill weight is the mass of powder in the vial; net peptide content is a separate figure that depends on salt form and residual water, as explained in peptide purity versus net peptide content.
Kisspeptin-10 is not yet on sale. It is listed so that laboratories in the United Kingdom can see what is planned and register interest; when it is in UK stock we send one email to say so, with the price, and nothing else. When it goes on sale it will be supplied on the same terms as every other material here: the price shown will be the total payable with UK delivery included, dispatched by Royal Mail Tracked 24 in unbranded packaging, with an order placed before 14:00 on a working day leaving that day where stock allows. Dispatch detail is on the shipping page. We supply research organisations, educational and commercial laboratories, and individuals purchasing for legitimate research.
Kisspeptin-10 will be supplied lyophilised, for storage at −20 °C protected from light. The sequence carries a tryptophan (Trp3), which is light- and oxidation-sensitive, and two asparagines (Asn2 and Asn4), which are the sites of deamidation in solution; the C-terminal amide is itself slowly hydrolysed in water. None of those pathways proceeds in a dry, sealed, cold and dark cake; see lyophilised peptide storage and stability.
Kisspeptin-10 is listed by NorthScientific strictly for laboratory research use. It is not a licensed medicine and has not been evaluated or approved by the MHRA; it is not a food, cosmetic or supplement; and it is not for human or veterinary consumption in any form. We provide no dosing, protocol or outcome guidance of any kind, and nothing on this page, in our guides or in correspondence should be read as such.
No. NorthScientific lists Kisspeptin-10 for laboratory research only; it is not for human or veterinary consumption in any form. We give no dosing or protocol guidance, and nothing on this page should be read as such.
We list it now so that laboratories can register interest, and we email once, when it is in UK stock and on sale. No date is promised: it goes on sale when supply meets the same standard as the rest of the catalogue, and the price is published then.
That the ten-residue sequence corresponds to positions 45 to 54 of the 54-residue peptide metastin, also known as kisspeptin-54. The listing is the ten-residue synthetic peptide only.
Because the material is a C-terminal amide rather than a free acid: the terminal carboxyl group is replaced by an amide. The amide is part of the defined structure and is reflected in the formula and mass given.
Not necessarily. The planned 5 mg is the fill weight of lyophilised powder in the vial; the peptide share depends on salt form and residual moisture. We do not publish an analysis for this material, so read the figure as fill weight.
