FAQ
PE-22-28 — frequently asked by B2B buyers.
What exactly is PE-22-28?
PE-22-28 is a synthetic heptapeptide (sequence GVSWGLR) corresponding to residues 22-28 of spadin, a sortilin-derived peptide, and is sometimes called mini-spadin. In preclinical research it is characterized as a selective TREK-1 potassium-channel inhibitor. All material is supplied strictly for laboratory and research use.
What purity and documentation do you provide?
Every lot ships with a Certificate of Analysis including RP-HPLC purity (typically >=98%) and mass-spectrometry identity confirmation matching the C35H55N11O9 / ~773.9 g/mol profile. Additional data such as residual-solvent, water-content, or endotoxin testing can be provided on request for OEM programs.
What vial size and MOQ are available?
The standard catalog format is 10 mg lyophilized vials with a minimum order of 50 vials. Custom fill weights and bulk quantities are quoted on RFQ for private-label and repeat buyers.
Can you private-label or customize PE-22-28?
Yes. We support OEM and private-label programs including custom vial fill, labeling, and packaging. Analogs and sequence modifications built on the GVSWGLR core can be scoped on RFQ, subject to feasibility review.
How is PE-22-28 shipped and handled for compliance?
Lyophilized material ships with documentation identifying it as a research-use-only chemical, not for human or veterinary use. Cold-chain or ambient shipping is selected by destination and transit time, and export paperwork is prepared per the buyer's jurisdiction.
