Kisspeptin

Kisspeptins are a family of peptides derived from the KISS1 gene product. They interact with the kisspeptin receptor, KISS1R, which appears in earlier scientific literature as GPR54. This receptor-peptide relationship is a central subject of kisspeptin research.

Research context

Early cell studies identified several kisspeptin fragments and examined their activity in cells expressing GPR54. The investigators measured changes in intracellular calcium and the phosphorylation of signaling proteins, connecting receptor engagement to responses inside the cell.

Different kisspeptin fragments can share a receptor target while remaining distinct molecules. Sequence length and terminal chemistry therefore matter when comparing published experiments. The family name alone does not identify a particular fragment.

Kisspeptin-receptor research sits within the broader study of hypothalamic signaling networks in cell and tissue models. Because KISS1R is a G protein-coupled receptor, experiments commonly track second-messenger production, receptor internalization, and downstream phosphorylation events, connecting peptide binding at the cell surface with measurable intracellular responses.

When comparing published results, fragment identity matters: kisspeptin-54, kisspeptin-14, kisspeptin-13 and kisspeptin-10 share a C-terminal receptor-binding region but differ in length, stability and behavior in experimental systems. Listing-level research interest centers on the defined 10-amino-acid fragment.

Quality, Purity and Documentation

Review the analytical documentation listed for the selected size. Reports describe the samples identified in them; they do not by themselves confirm that current stock matches those samples. If no matching report is listed, contact Prestige Peptides for documentation before ordering.

Planned format

Kisspeptin 10mg is planned as a lyophilized (freeze-dried) powder in a sealed 10mg vial. Lyophilization removes water under vacuum at low temperature, producing a dry preparation suited to controlled laboratory storage. This listing is pending release; the notification form on this page registers interest for availability updates.

Storage and handling

Store lyophilized vials at -20°C or below, protected from light and moisture. Allow sealed vials to equilibrate to room temperature before opening to limit condensation inside the vial. Once opened, handle with clean laboratory technique, minimize exposure to ambient humidity, reseal promptly, and record the lot number in laboratory documentation for traceability.
