Product Description
The PE-22-28 peptide is a synthetic heptapeptide and an optimized analogue of Spadin-derived from the sortilin propeptide-that acts as a highly selective antagonist of TREK-1 potassium channels. Compared to the parent molecule Spadin, it exhibits greater inhibitory potency and enhanced in vivo stability. Capable of blocking neuronal TREK-1 channels and increasing neuronal excitability, it serves as a valuable tool peptide for ion channel research.
Supplied as a lyophilized powder in a vial, this product is designed for use in neuroscience experiments involving cellular and animal models. It modulates serotonin signaling and influences hippocampal neurogenesis and synaptic plasticity, making it a useful tool for investigating mechanisms related to mood and neuronal function.

FAQ
1. Can the vial of lyophilized peptide powder be opened and weighed immediately upon receipt?
Opening the vial directly at room temperature is not recommended; temperature differences can cause condensation, leading the peptide to absorb moisture. The unopened vial should be allowed to equilibrate to room temperature before opening and weighing.
2. How should the remaining lyophilized peptide powder be handled after the vial is opened?
Ideally, weigh out the entire amount needed in one go. If any remains, seal the vial immediately to protect the contents from moisture and air; avoid repeated opening to prevent peptide degradation and ensure experimental reproducibility.
3. How many freeze-thaw cycles can the peptide withstand?
It is recommended to limit this to no more than 2–3 cycles, as freeze-thaw processes increase the risk of peptide chain degradation. After reconstitution, it is best to aliquot the solution into single-use portions.
