Overview+

A neuropeptide encoded by the KISS1 gene and studied as a key upstream regulator of the hypothalamic–pituitary–gonadal axis. Research focuses on its role in GnRH release and reproductive endocrine signaling.

History+

Originally identified as a metastasis-suppressor gene product (metastin), kisspeptin was later characterized in the mid-2000s as the ligand for GPR54/KISS1R and recognized as a master regulator of reproductive endocrine function.

Structure & specifications+
CAS #: 374675-21-5
Formula: C₆₃H₈₃N₁₇O₁₄
MW: 1302.45 g/mol
PubChem ID: 16130572
Research findings+

Studied in endocrine and neurological models for KISS1R activation, GnRH-neuron stimulation, LH/FSH release, and reproductive-axis signaling.

Key areas of research
  • →Endocrine: KISS1R/GPR54 signaling, GnRH release
  • →Reproductive: LH/FSH pulsatility, HPG-axis dynamics
  • →Neurological: Central reproductive control pathways

Frequently asked questions

What's the actual amount in each vial?+
Each vial contains the labeled mass of lyophilized peptide. Selected sizes appear above the price.
Are additional supplies needed?+
Reconstitution requires bacteriostatic water and appropriate sterile research labware – not included.
How long does a vial last?+
Sealed lyophilized vials are stable at −20°C for 24 months. Once reconstituted, store at 2–8°C and use within 28 days.
Does the product come with instructions?+
Each shipment includes the batch-specific Certificate of Analysis and recommended handling protocol.
What purity level is guaranteed?+
≥ 99% by reverse-phase HPLC (UV-220nm), confirmed via ESI-TOF mass spectrometry.
How should I store these products?+
Store sealed vials at −20°C, protected from light. Reconstituted solutions at 2–8°C.
What are peptides and how do they work?+
Peptides are short chains of amino acids that occur naturally in organisms, where they act as messengers in many biological systems. While some peptides have been developed for medical use, laboratory research focuses on understanding their activity at the cellular level, examining how they impact essential processes in vitro.
Do these products come with instructions?+
Products from Fast Track Labs are supplied without usage instructions, as they are designated solely for in vitro laboratory research and prohibited by law for human or animal consumption. Any misuse or unlawful application of these products will result in permanent denial of service.
How long do products take to deliver?+
Orders are typically processed and shipped within 24 hours, Monday through Saturday. Delivery times vary by location, but most domestic orders arrive within 3–5 business days. You'll receive tracking information as soon as your order ships.
