Kisspeptin Nasal Spray

Direct Anti Peptide offers Kisspeptin Nasal Spray at ≥98% purity, formulated exclusively for qualified laboratory and scientific research applications. This intranasal peptide delivery format is designed to support advanced in-vitro and in-vivo research investigations into hypothalamic-pituitary-gonadal axis signalling. For research use only. Not for human or veterinary use. Not for clinical, diagnostic, or consumptive applications.

Product Overview

Kisspeptin Nasal Spray represents a sophisticated peptide research format that combines the biological activity of kisspeptin with a precisely engineered intranasal delivery system. Kisspeptin — encoded by the KISS1 gene — is a neuropeptide family recognised for its foundational role in neuroendocrine regulation, particularly within the hypothalamic-pituitary-gonadal (HPG) axis. Research into kisspeptin signalling has expanded considerably over the past two decades, making this compound a high-priority subject in reproductive neuroendocrinology, hormonal regulation, and fertility science. Direct Anti Peptide supplies this research-grade nasal spray format to accredited laboratories, academic institutions, and professional research teams seeking consistent, high-purity peptide solutions for controlled experimental use.

Peptide Structure & Amino Acid Sequence

Kisspeptin belongs to the RF-amide peptide superfamily and is derived from the proteolytic cleavage of the 145-amino-acid precursor protein encoded by the KISS1 gene. The primary bioactive fragment studied most extensively in research contexts is Kisspeptin-10 (KP-10), a decapeptide with the C-terminal RF-amide motif critical for binding to its cognate receptor, KISS1R (also known as GPR54). Longer isoforms — including KP-13, KP-14, and KP-54 — are also of significant research interest. The nasal spray format supplied by Direct Anti Peptide is formulated to preserve the structural integrity of the active peptide sequence throughout storage and experimental deployment, supporting reliable receptor-binding assays and signalling pathway investigations.

• Solubility: Aqueous-based formulation optimised for nasal spray delivery
• Molecular Activity: Agonist at KISS1R; stimulates GnRH pulse release in research models

Purity & Analytical Verification (HPLC & MS)

Every batch of Kisspeptin Nasal Spray produced for Direct Anti Peptide undergoes rigorous analytical testing to confirm identity, purity, and concentration. High-Performance Liquid Chromatography (HPLC) analysis verifies that purity meets or exceeds the ≥98% threshold, while Mass Spectrometry (MS) confirms the correct molecular mass and peptide sequence integrity. These dual-verification protocols ensure that each unit dispatched to research facilities meets the exacting standards required for reproducible experimental outcomes. Certificates of Analysis (CoA) are available upon request, providing full traceability for laboratory documentation and institutional compliance requirements.

Quality Control & Lyophilization Integrity

The nasal spray formulation undergoes strict quality control procedures at every stage of production. While the spray format is supplied as a prepared aqueous solution rather than a lyophilised powder, the manufacturing process employs pharmaceutical-grade excipients and sterile filtration techniques to maintain peptide stability and prevent degradation. Batch-level quality control testing includes pH verification, particulate matter assessment, and microbial limit testing, ensuring that each unit meets the high standards expected by professional research teams. Direct Anti Peptide maintains full batch traceability across all production runs.

Safety, Handling & Laboratory Precautions

Kisspeptin Nasal Spray is supplied strictly for use by trained research professionals operating within appropriately equipped laboratory environments. Standard laboratory safety protocols must be observed at all times when handling this product. Researchers should wear appropriate personal protective equipment (PPE), including gloves and eye protection. This product must not be used outside of a controlled research setting. It is not approved for administration to humans or animals outside of formally sanctioned, ethics-approved research protocols where applicable under local regulatory frameworks. Any exposure incidents should be managed according to institutional health and safety procedures.

Reconstitution, Packaging & Storage

Kisspeptin Nasal Spray is supplied ready-to-use in a precision-dose nasal spray bottle, eliminating the need for reconstitution prior to research application. The product should be stored at 2–8°C (refrigerated) when not in active use, and protected from direct light and excessive heat. Do not freeze the prepared spray solution. Ensure the spray mechanism is primed correctly before experimental use in accordance with laboratory protocols. Each unit is securely packaged to maintain product integrity during transit and storage. Researchers should refer to the accompanying documentation for full storage guidance and handling notes.

Intended Research Use & Market Positioning

Kisspeptin Nasal Spray is positioned as a premium research tool for scientists and institutions investigating HPG axis regulation, gonadotropin-releasing hormone (GnRH) pulse dynamics, reproductive neuroendocrinology, and hormonal signalling pathways. Published literature has extensively characterised kisspeptin’s role in modulating luteinising hormone (LH) and follicle-stimulating hormone (FSH) secretion in research models, making it a compound of considerable scientific interest. Direct Anti Peptide supplies this format to support cutting-edge research into these mechanisms under strictly controlled laboratory conditions.
