What Is PE22-28 Peptide?

Within our Neuropeptide Research range, we offer PE22-28 Peptide as a research-grade compound for laboratory and in vitro use. PE22-28 Peptide is a synthetic spadin analogue TREK-1 channel antagonist. Researchers apply it in laboratory and in vitro research settings. We produce it to a defined synthesis specification. Therefore, we supply it exclusively to qualified researchers.

Research Applications

PE22-28 truncates spadin, a peptide that itself derives from the sortilin propeptide. Researchers have studied this truncated form for its activity at TREK-1 potassium channels.

This compound sits within the wider body of research on neuropeptide research, an area where researchers commonly investigate structure-activity relationships and receptor selectivity. Working from a single, well-defined reference batch reduces one source of variability when a laboratory repeats or extends a study. On the other hand, reconstitution technique and storage practice remain variables researchers need to control independently.

Purity, Testing & Quality Assurance

We carry out third-party testing on every batch to confirm both purity and identity, and we make a Certificate of Analysis available for researchers who request one. This step matters most when a study needs replication across sites, since independent verification reduces the chance that a variation in results comes from the starting material itself. We retain documentation for each production run for future reference.

Storage & Reconstitution

We typically supply this compound as a lyophilised powder. Researchers should reconstitute it with an appropriate solvent, such as bacteriostatic water, immediately before use. Once in solution, it loses stability at room temperature more quickly, so we recommend refrigerated storage and prompt use. We also suggest reconstituting only the amount needed for a given experiment, since repeated freeze-thaw cycles can affect integrity. The unopened, lyophilised material stays comparatively stable when stored according to the conditions listed on the Certificate of Analysis.

Usage Restrictions

This product serves laboratory and in vitro research only. It is not a medicine, and researchers must not use it for human consumption, animal consumption, diagnosis, or therapy. For independent chemical reference data, researchers can consult the PubChem compound database.
