Kisspeptin-10 10mg — Vial Spec, Reconstitution Math & COA

Overview of Kisspeptin-10 10mg Vial Specifications

A 10mg vial of Kisspeptin-10 contains precisely 10.0 milligrams of the active decapeptide sequence (Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH2) stabilized as a vacuum-sealed lyophilized cake. This specific mass option is engineered for high-throughput assay protocols, longitudinal rodent models, and laboratories that require a consistent single-lot reagent standard across multiple experimental replicates.

Kisspeptin-10 represents the minimal biologically active C-terminal sequence derived from the precursor protein encoded by the KISS1 gene. In preclinical research, this peptide serves as a primary tool for probing neuroendocrine pathways, specifically targeting the G-protein coupled receptor KISS1R (formerly known as GPR54). Evaluating Kisspeptin-10 in a 10mg format minimizes lot-to-lot variance across extended experimental timelines.

To review current batch availability or select alternate fill sizes, researchers can explore our comprehensive catalog of all peptides or consult the primary Kisspeptin-10 product page. If a specific 10mg mass format is out of stock, PX1 Research maintains equivalent high-purity yield standards across all available unit volumes.

Catalog Availability and Sourcing Guidelines

PX1 Research manufactures and packages research-grade compounds under rigorous quality management systems in ISO 17025 accredited and GMP-compliant USA facilities. While the 10mg mass specification is tailored for high-volume research protocols, active inventory varies based on synthesis schedules and analytical batch releases.

If the 10mg vial configuration is temporarily unlisted on the main Kisspeptin-10 page, research teams can utilize standard 5mg vials to achieve identical molar concentrations without altering baseline experimental conditions. Every unit shipped from PX1 Research—regardless of total peptide mass—undergoes identical third-party purity testing, HPLC characterization, and endotoxin quantification.

Reconstitution Mathematics for 10mg Lyophilized Mass

Accurate reconstitution of a 10mg Kisspeptin-10 vial requires precise volumetric calculations to achieve desired working concentrations for laboratory liquid-handling systems. Because 10mg equals 10,000 micrograms (mcg), adjusting the volume of diluent—typically sterile bacteriostatic water or standard laboratory saline—directly determines the final concentration per microliter (µL).

When adding 1.0 mL of diluent to a 10mg lyophilized cake, the resulting solution yields a concentration of 10,000 mcg/mL, or 10 mcg/µL. Introducing 2.0 mL of diluent produces a concentration of 5,000 mcg/mL (5 mcg/µL). For larger volume protocols requiring broader volumetric delivery, adding 3.0 mL of diluent results in approximately 3,333.33 mcg/mL (3.33 mcg/µL).

To eliminate manual calculation errors and ensure exact micro-volume dosing across benchtop pipetting platforms, investigators should utilize our interactive reconstitution calculator. Correct volumetric alignment is critical for maintaining consistent molarity in both static cell culture wells and automated animal administration setups.

Laboratory Aliquoting Strategy and Freeze-Thaw Prevention

Once reconstituted, peptide solutions undergo rapid physical degradation if subjected to repeated freeze-thaw cycles. Thermal fluctuations break peptide bonds, disrupt secondary structures, and promote aggregation, which alters effective concentration and skews experimental outcomes.

To optimize stability, laboratories handling a 10mg Kisspeptin-10 vial should execute a strict aliquoting protocol immediately following reconstitution. Reconstituted solution should be divided into single-use micro-aliquots using sterile, low-binding polypropylene tubes. These aliquots should be stored at -20°C or -80°C until immediately prior to experimental use.

When an aliquot is thawed for an assay, any remaining fluid should be stored at 2°C to 8°C and consumed within 24 to 48 hours, or disposed of according to institutional bio-reagent protocols. Re-freezing thawed liquid phase Kisspeptin-10 is strongly discouraged due to rapid structural breakdown.

Storage Conditions and Physical Handling Requirements

Unreconstituted (lyophilized) Kisspeptin-10 10mg vials must be preserved under climate-controlled conditions to guarantee chemical stability. For short-term transit or storage prior to assay setup, intact vials should be stored at 2°C to 8°C protected from light. For long-term preservation exceeding 30 days, intact lyophilized vials should be maintained at -20°C.

During reconstitution, diluent must be directed against the glass inner wall of the vial rather than sprayed directly onto the lyophilized cake. Gentle side-to-side rotation should be applied until complete dissolution occurs. Mechanical agitation, vigorous shaking, or ultrasonic vortexing must be avoided, as high shear forces can denature delicate peptide chains.

Lot-Matched COA Verification: HPLC and Mass Spectrometry

PX1 Research enforces batch-specific quality assurance on every production run. Every individual fill size—including 5mg and 10mg vial lots—is assigned a unique lot number linked to its corresponding Certificate of Analysis (COA).

To review analytical data for a specific lot, researchers can visit our dedicated COA lookup portal. Each COA provides raw spectral output from High-Performance Liquid Chromatography (HPLC) to verify chemical purity (>98%), Matrix-Assisted Laser Desorption/Ionization (MALDI-TOF) or LC-MS mass spectrometry to confirm exact molecular mass (1302.5 g/mol), and Limulus Amebocyte Lysate (LAL) testing to certify endotoxin levels fall strictly below 0.01 EU/mg.

This level of analytical transparency ensures that research facilities receive unadulterated, highly stable compounds free from synthetic trifluoroacetic acid (TFA) salts or organic solvent residues that could otherwise compromise delicate cell culture models.

Upstream HPG Axis Receptor Targeting and Signaling Mechanism

In neuroendocrine research models, Kisspeptin-10 functions as a potent endogenous agonist for the KISS1R receptor located on gonadotropin-releasing hormone (GnRH) neurons within the hypothalamus. Preclinical rodent models demonstrate that binding of Kisspeptin-10 to KISS1R activates the Gq/11-coupled pathway, stimulating phospholipase C (PLC) and downstream intracellular calcium mobilization.

This intracellular signal triggers pulsatile secretion of GnRH into the hypophyseal portal system, which subsequently stimulates the anterior pituitary gland to synthesize and release Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH). In vitro tissue slice cultures show that Kisspeptin-10 acts as the master upstream regulator of the entire reproductive axis.

By mapping the signaling cascade of Kisspeptin-10, investigators gain insight into the broader homeostatic control of gonadotropin release, metabolic feedback loops, and neuroendocrine signaling networks. Further reading on comparative neuroendocrine pathways is accessible through the PX1 research library.

Comparative Analysis: Kisspeptin-10 vs. Related Neuroendocrine Regulators

When designing protocols to investigate the HPG axis, researchers frequently compare Kisspeptin-10 against direct pituitary stimulators and synthetic GnRH analogues. While Kisspeptin-10 acts upstream at the hypothalamic neuronal level, compounds such as gonadorelin act directly at the pituitary level to induce immediate LH and FSH release. Conversely, superagonist peptides like triptorelin bind pituitary GnRH receptors with high affinity, causing initial surge dynamics followed by receptor down-regulation.

Another relevant comparative research peptide is GnRH, which operates immediately downstream of kisspeptin signaling. Selecting between these compounds depends on whether an experiment aims to isolate upstream hypothalamic signal transduction (Kisspeptin-10), direct pituitary receptor kinetics (Gonadorelin), or receptor desensitization mechanics (Triptorelin).

Selecting Between 5mg, 10mg, and Bulk Volume Formats

Choosing the ideal vial specification depends on experimental duration, sample size, and liquid-handling automation. A 10mg Kisspeptin-10 vial is highly efficient for automated robotic pipetting stations or high-density microplate assays where large working volumes of standardized reagent are required simultaneously.

For smaller pilot projects, exploratory binding assays, or multi-investigator shared facilities, smaller 5mg vials may be preferable to minimize the time a reconstituted solution remains in liquid phase storage.
