Kisspeptin — compound background
Decapeptide (Kisspeptin-10), KISS1 gene product fragment
Kisspeptin-10 is the C-terminal decapeptide of the KISS1 gene product, active at the KISS1 receptor (GPR54). It sits at the top of the reproductive signalling axis, studied for triggering GnRH release. The parent protein was first described as a metastasis suppressor, hence the older name metastin.
Solubility & reconstitution
Water-soluble and dissolves readily. The sequence carries a tryptophan, so protect solutions from prolonged light exposure once reconstituted.
Commonly worked at 1-2 mg/mL.
Storage
Sealed powder stable at -20 °C. Refrigerate at 2-8 °C and protect from light.
Commonly worked with for 2-3 weeks at 2-8 °C, shorter if exposed to light.
Stability
The tryptophan is the vulnerability that sets it apart from oxidation-insensitive short peptides — light discipline matters here.
Reading the Certificate of Analysis
Confirm the mass near 1302.5 Da and scan for a companion peak 16 Da heavier, which indicates tryptophan oxidation.
