KISSPEPTINReproductive peptide

Kisspeptin price comparison

Kisspeptin is a reproductive-axis signaling peptide, the product of the KISS1 gene, that acts on the KISS1R (GPR54) receptor and is studied in laboratory models for its role in regulating GnRH neuron activity and upstream control of the reproductive endocrine system. Multiple fragment forms (such as kisspeptin-10 and kisspeptin-54) are used as reference materials in neuroendocrine and receptor-signaling research. This index tracks research-use-only vendor pricing for Kisspeptin to help researchers compare cost across suppliers.

Why compare $/mg for Kisspeptin?

Per-mg prices for Kisspeptin vary because vendors differ in synthesis scale, stated purity, salt form and net-peptide content, and how they package and ship a hygroscopic lyophilized product. Comparing normalized $/mg across suppliers lets a researcher weigh headline vial price against documented purity and actual peptide mass, rather than paying more for a nominally cheaper vial.

Reading the COA

For Kisspeptin, confirm identity by mass spectrometry against the expected monoisotopic/average mass of the specific fragment ordered (kisspeptin-10 versus kisspeptin-54 differ substantially), since fragment length is a common source of mislabeling. Check that HPLC purity is stated (commonly 95%+ or 98%+ for reference-grade material) with the trace attached, and look for a net peptide content figure and counterion identity. Likely impurities to watch for include truncated or deletion sequences, incompletely deprotected species, and TFA/acetate salt contributing to non-peptide mass.

FAQ

How should lyophilized Kisspeptin be stored in the lab?
Lyophilized Kisspeptin is a research-use-only material that is typically kept sealed and desiccated at -20C or colder, protected from light and moisture, since the peptide is hygroscopic. Vendor storage statements often note allowing a sealed vial to reach room temperature before opening to reduce condensation onto the powder. Always follow the specific vendor's storage and stability statement on the COA for the lot you receive.
What is a COA and what should I check on one for Kisspeptin?
A Certificate of Analysis (COA) is the lot-specific document a vendor issues to characterize the material. For Kisspeptin, verify the mass-spectrometry result matches the expected mass of the exact fragment you ordered, confirm the HPLC purity percentage with an attached chromatogram, and check the stated net peptide content, counterion/salt form, and lot number. These fields verify identity and purity of the material, not any functional outcome.
Why do per-mg prices for Kisspeptin differ so much between vendors?
Differences come from synthesis scale and yield, stated purity grade (98%+ material costs more to produce than 95%), and whether the listed milligram figure refers to gross weight or net peptide after salt and moisture are subtracted. Analytical documentation, quantity discounts, and shipping/cold-chain handling also shift the effective $/mg, which is why normalizing to net peptide mass makes cross-vendor comparison meaningful.
