What is Kisspeptin-10?
Kisspeptin-10 is a synthetic linear decapeptide with an amidated C-terminus. It is catalogued under CAS 374675-21-5 and PubChem CID 25240297, with the molecular formula C63H83N17O14 and a molecular weight of 1302.4 g/mol.1
The material described on this page is a synthetic peptide intended as a laboratory reagent.
Composition
The ten residues are asparagine (×2), phenylalanine (×2), arginine, glycine, leucine, serine, tryptophan and tyrosine. Counting a free amino end and an amidated carboxyl end, the peptide carries a calculated net charge of about plus two at pH 7.
The sequence contains tryptophan, which general peptide guidance identifies as prone to air oxidation.2 This is one reason the material is stored dry and sealed.
Handling
Kisspeptin-10 is a dry solid as received in the laboratory. General handling guidance for lyophilized peptides applies.2
How each lot is tested
Each lot in the My Oasis Labs catalogue is tested by an independent third-party laboratory.3 The Kisspeptin-10 certificate page names the testing laboratories and lists each lot's purity, net content and test date. Three measurements are reported.
Identity
Mass spectrometry
Checks that the measured molecular mass matches Kisspeptin-10. The calculated monoisotopic mass is 1301.63 Da.1
A matching mass is consistent with the expected composition. It does not confirm the order of residues.
Purity
High-performance liquid chromatography (HPLC)
Separates the material from synthesis-related impurities. Purity is reported as the main peak's share of the total detected signal.
Reported per lot on the Certificate of Analysis.
Quantity
Net content
Measures the mass of material actually present in the sample tested.
Reported per lot on the Certificate of Analysis.
Technical notes
What does the Certificate of Analysis confirm?
Identity by mass spectrometry, purity by HPLC, and the net content of the sample. Mass spectrometry confirms molecular mass, not the order of residues.
Why do molecular weights for Kisspeptin-10 differ slightly between sources?
The figure of 1302.4 g/mol is for the form described in the cited PubChem record. Salt forms carry extra counter-ion mass and are often registered separately.
Why is the material freeze-dried?
Peptides are most stable as dry solids. Moisture reduces long-term stability, so the material is lyophilized and kept sealed until use in the laboratory.
