Kisspeptin-10 and the GnRH pulse generator, reproductive endocrine research
The discovery of KISS1's role in puberty, GPR54 signaling, and what reproductive-research labs need from a verified reference standard.
In a Canadian research-peptide context, Kisspeptin-10 sits within the reproductive class of reference standards. This post collects what HPLC-verified labs need to know about sourcing, storing, and reproducibly using this material, drawn from public literature. Kisspeptin-10 is not currently stocked in the Pure North Peptides catalog, the handling notes below apply to verified reference material from any qualified supplier.
Why Kisspeptin matters
Pure North publishes laboratory reports for the samples and vial sizes listed in Lab Results. Each report identifies its method, reference, area purity and measured content. Open the matching product page to check coverage for the size you select. A report does not cover every size or future lot; contact customer service if your vial reference differs. Bacteriostatic water has no COA.
The protocol short-version
For Canadian research labs working with Kisspeptin-10, the lifecycle is: on receiving the vial, transfer it immediately to a research-grade −20 °C freezer, reconstitute in sterile bacteriostatic water at the working concentration your protocol specifies, and use within a validated, material-specific stability window. Avoid repeated freeze-thaw cycles, the effect depends on the material and handling conditions.
Cross-batch reproducibility
Match the compound, vial size and lot or assigned reference before relying on a report. If a reference differs from the vial label, contact purenorthpeptides@proton.me for the documented connection. A report does not cover another size or future lot. Keep the original report and research records when investigating unexpected results; a published COA does not establish a retain-sample programme.
Sourcing in Canada
Kisspeptin-10 is not currently stocked by Pure North Peptides. For the reference standards we do carry, Pure North is Canadian-based and ships across Canada via Canada Post Xpresspost, orders are dispatched within 24-48 hours, with typical transit around 4 days. Free shipping over $300 CAD; flat $30 below that. Browse the current catalog at /products/.
