Description
PE-22-28 10mg
PE-22-28 is a synthetic 7-amino acid peptide representing a fragment of spadin, a peptide derived from the propeptide of sortilin (sortilin-derived neuropeptide). With the sequence Val-Leu-Gly-Leu-Gly-Asn-Leu, PE-22-28 has been studied in cellular biology and biochemical research literature examining peptide chemistry and cellular signaling research.
Each vial contains 10mg of lyophilized PE-22-28 in a sealed 3mL glass vial, verified through Mile High Compounds’ three-tier quality protocol: 7x independent third-party analytical testing, 4-vial batch conformity verification, and comprehensive heavy metal screening.

Research Context
PE-22-28 is utilized in research applications involving peptide chemistry, cellular signaling research, and cellular research applications. As a spadin fragment peptide, PE-22-28 represents a research subject in the broader field of peptide truncation chemistry — specifically the use of small peptide fragments to study structure-activity relationships within larger parent peptides and cellular signaling pathway research.
This compound is supplied exclusively for in vitro research and laboratory investigation by qualified researchers in appropriate research environments.
Analytical Verification
Every batch undergoes Mile High Compounds’ comprehensive analytical protocol:
- High-Performance Liquid Chromatography (HPLC) for purity quantification
- Mass Spectrometry (MS) for molecular weight and identity confirmation
- 14-day sterility testing
- Endotoxin analysis
- 4-vial batch conformity verification — statistically robust consistency testing across each production batch, exceeding the industry-standard single-vial sampling approach
- Heavy metal screening for lead, arsenic, cadmium, mercury, and additional trace metals
- Container and seal integrity verification
Batch-specific Certificates of Analysis (COAs) accompany every order, documenting full testing results across all verification protocols.
Reconstitution and Storage
- Lyophilized storage: Cool, dry location away from direct light; -20°C for long-term stability
