Kisspeptin-10 in brief

Kisspeptin-10 comes in 2 strengths from 5mg to 10mg per vial, each a sealed box of ten, from $52.82 to $90.74 a box. Per mg the spread is narrow: KS10 (10mg x 10 vials) works out at $0.907 per mg against $1.056 per mg for KS5 (5mg x 10 vials), 14 percent less for the same mg, because the vial, the fill and the testing cost about the same whatever the vial holds.

Nothing is on the shelf today: every strength is made to order, about four weeks, in any quantity.

What Kisspeptin-10 is

Kisspeptin-10 is the ten-residue C-terminal fragment of kisspeptin, YNWNSFGLRF-NH2, average mass 1302.5, amidated and supplied as the acetate. It carries the RF-amide motif at its C-terminus that defines the family.

Two asparagines near the N-terminus, at 2 and 4, are its deamidation sites, and the tryptophan at position 3 is the light-sensitive residue; between them they give the related substances to expect. There is no methionine. It is moderately hydrophobic for its size, with four aromatic residues: tyrosine 1, tryptophan 3 and phenylalanines 6 and 10. Store dark and cold.

Registry and identity

  • Kisspeptin-10 is residues 112 to 121 of the human KISS1 precursor (UniProt Q15726), the C-terminal decapeptide it shares with kisspeptin-13, kisspeptin-14 and kisspeptin-54, also called metastin (residues 68 to 121); phenylalanine 121 is amidated. UniProt
  • Catalogues also call it metastin (45-54), human metastin 45-54 and KP-10, filed by FDA as UNII FS1N52VS3S, by CAS as 374675-21-5, in PubChem as CID 25240297 and in ChEMBL as CHEMBL376756. FDA GSRS, PubChem
  • Its monoisotopic mass is 1301.631, so its [M+H]+ ion gives m/z 1302.638 and its [M+2H]2+ ion 651.823; a chain with a free C-terminal acid in place of the amide weighs 0.984 more. PubChem
  • It is also listed by suppliers as the trifluoroacetate salt; acetate is a line of the specification here, not a certificate result, so ask the desk which salt a batch is. PubChem

A listing in these registers identifies a substance; it is not an approval of this line.

Kisspeptin-10 beside Gonadorelin and Triptorelin

Kisspeptin-10 works out at $0.907 per mg at 10mg (KS10), its lowest by the single box. Its neighbours, on price alone: Gonadorelin at $0.893 per mg at 5mg (GND5, in 50-box lots), 1,182.3 g/mol; Triptorelin at $1.403 per mg at 2mg (TA/G2, in 50-box lots), 1,311.5 g/mol.

Reading a Kisspeptin-10 certificate of analysis (COA)

Identity by mass. Average mass 1302.5 (C63H83N17O14). In electrospray the protonated ions come near m/z 1303.5 (singly charged), m/z 652.2 (doubly charged); on our certificates the measured mass is matched to the calculated average mass, within about one unit.

  • Oxidation: 1 tryptophan, which oxidises to kynurenine and hydroxy forms under light. Kynurenine makes the chain 4 heavier and a hydroxy tryptophan 16.
  • Deamidation: 2 asparagines. The deamidated form is 0.984 heavier and a little more negatively charged, inside the tolerance of the average-mass line; telling it apart takes a high-resolution mass, which the certificate does not carry.
  • Charge: near neutral pH about +2, basic.

Buy Kisspeptin-10 in bulk

Kisspeptin-10 is sold in bulk by the sealed box of ten vials, and every account starts at list price. Two discounts can lower it, the size of one order (from $5,000 of goods) or the account’s tier (from lifetime paid spend), and the better one applies, never both. Priced below on KS10, 10mg x 10 vials, the best-priced strength.

Questions about Kisspeptin-10

What are Kisspeptin-10’s sequence, formula, molecular weight and CAS number?

YNWNSFGLRF-NH2 (Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH2), ten residues ending in an amidated phenylalanine: C63H83N17O14, molecular weight (average mass) 1,302.5, CAS 374675-21-5. FDA’s GSRS keeps it as UNII FS1N52VS3S and PubChem as CID 25240297. KP-10 and metastin (45-54) are other names for these same ten residues.

Why is Kisspeptin-10 also called metastin (45-54), and what do the numbers count?

They count along metastin, kisspeptin-54, the KISS1 precursor’s residues 68 to 121 (UniProt Q15726). Kisspeptin-10 is the last ten of them, precursor 112 to 121, and taking 67 from a precursor number gives metastin’s own count, 45 to 54. In that count tyrosine 1 is 45, the asparagines at 2 and 4 are 46 and 48, tryptophan 3 is 47, arginine 9 is 53, and the amidated phenylalanine that closes both chains is 54. Kisspeptin-13 and kisspeptin-14 end on the same ten.

How much does Kisspeptin-10 cost?

From $52.82 a sealed box of 10 vials, up to $90.74 for the largest strength sold singly, which works out at $0.907 per mg at its best-priced size. To a US address, freight is included from $1,000 of goods; below that it is the carrier’s rate for the carton or a flat $35.00, and to another country the desk quotes it; either way the figure is on the proforma before you pay. Every strength and its price per vial is in this page’s price table.

Which Kisspeptin-10 size is cheapest per mg?

KS10, 10mg x 10 vials, at $0.907 per mg, which is 14 percent less per mg than KS5, at $1.056 per mg. Larger vials cost less per mg across this range, so match the vial to the size of the work first, then compare per mg.

Can I buy a single vial of Kisspeptin-10?

No. One sealed box of ten vials is the smallest quantity of a regular line; for Kisspeptin-10 that is KS5, 5mg x 10 vials, at $52.82. A first order must reach $100 of goods, so KS5 alone takes two boxes ($105.64) or one box beside other lines. A box is sealed at fill with its batch number on it, and splitting one would break the link between the vials and their certificate.

Which Kisspeptin-10 strengths are in stock today?

None today. Every strength is made to order, about four weeks, and can be ordered in any quantity.

How is Kisspeptin-10 stored?

At minus 20 degrees Celsius, dark and dry. Lyophilised powder tolerates a short spell at ambient temperature in transit, which is why boxes ship without ice. Storage and handling.

What is in a box of Kisspeptin-10?

Ten sealed vials of one strength, each labelled with the product code, the strength and the batch number; the trade also calls a box a 10-vial kit. Kisspeptin-10 is supplied as a powder in a sealed glass vial and in no other presentation. Boxes are not split.

Is a certificate of analysis (COA) provided for Kisspeptin-10?

Yes. For Kisspeptin-10 the batch certificate reports its purity, net content and identity by mass spectrometry. The other lines on this page are the specification it is made to, and the desk answers for them on a particular batch. The certificate is sent with the shipment, and again on request, and any batch number can be verified on the certificate page.

Is this for human use?

No. Everything here is supplied for laboratory research only, to trade accounts, and is not for human or animal consumption. The research-use page sets out who can buy and what is not sold.
