Compound Overview
PE 22-28 is a synthetic heptapeptide composed of the amino acid sequence Gly-Val-Ser-Trp-Gly-Leu-Arg. It is structurally defined as a short linear peptide fragment with a specific molecular weight and charge profile suitable for chromatographic and mass spectrometric identification in laboratory research workflows.
In research environments, PE 22-28 is evaluated for structural confirmation, peptide stability profiling, and analytical characterization using validated HPLC and LC-MS methodologies. Experimental literature classifies it within short regulatory peptide research systems investigated under controlled in vitro and preclinical model conditions. All data referenced on this page is derived from published preclinical animal and in vitro studies. No human clinical trials have established approved uses for PE 22-28 as a research compound.

Compare to Related Compounds
Pinealon
- PE 22-28 is a seven–amino acid linear peptide, whereas Pinealon is a short tripeptide fragment with a distinct sequence composition.
- These compounds differ in amino acid length, molecular weight class, and chromatographic behavior in validated analytical systems.
DSIP
- PE 22-28 and DSIP are both short peptides, but they differ in primary sequence, molecular weight, and physicochemical properties.
- Analytical differentiation is based on sequence architecture and mass spectrometry profiling characteristics.
Handling & Storage
Lyophilized Stability:
When stored sealed in a dry environment protected from light, lyophilized peptide material may maintain chemical stability for up to 12 months at controlled room temperature. For maximum long-term preservation, storage at -20°C is recommended.
Post-Reconstitution Stability:
Following reconstitution under sterile laboratory conditions, the solution may maintain stability for up to 30 days when stored at 2–8°C. Minimize repeated freeze–thaw cycles and protect from light to preserve peptide integrity.
Handling:
Allow vial to equilibrate to room temperature before opening to prevent moisture condensation. Use sterile technique throughout preparation.
