Where can PE-22-28 peptide be purchased for research?

PE-22-28 is available directly from Real Peptides, a United States supplier of research-use-only compounds. The peptide is stocked domestically, listed on this product page, and dispatched from company-operated facilities in Florida and California. Orders are placed online, and the published certificate of analysis for the lot in stock can be reviewed before a purchase is completed.

What quantity is supplied when PE-22-28 is for sale here?

This listing covers a single vial containing 8mg of lyophilized PE-22-28. Only that size is offered on this page. Any additional research peptides or vial sizes carried by Real Peptides appear as their own separate catalog listings, each with its own independently tested lot and its own published certificate of analysis.

Is a certificate of analysis published for PE-22-28?

Yes. A certificate of analysis for the exact lot in stock is published in the lab-results section of the site and is accessible before purchase. The certificate reports the identity and purity findings returned by the independent laboratory for that specific batch, so researchers can match documentation to the vial they receive.

How is the purity of PE-22-28 verified?

Each production batch is submitted to an independent analytical laboratory rather than assessed in-house only. Testing covers peptide identity and purity, and the resulting report is published for that lot. Figures shown on the certificate reflect that batch alone, which is why the lot-specific document is posted instead of a generic specification sheet.

Who is eligible to buy PE-22-28?

Purchasers confirm at checkout that they are 21 years of age or older and that the material is being acquired for laboratory research purposes only. No institutional affiliation or professional credential is required. PE-22-28 is sold as a chemical reagent and must not be acquired for human consumption, veterinary use, or any clinical application.

How quickly does PE-22-28 ship, and from where?

In-stock PE-22-28 ships from warehouses in Florida and California, typically within 24 hours of order confirmation on business days. Domestic dispatch from two coasts helps shorten transit for most United States research addresses. Tracking details are issued once the parcel is handed to the carrier so shipments can be monitored to arrival.

How should PE-22-28 be handled once it arrives?

The vial arrives as a lyophilized powder. Laboratories generally keep sealed lyophilized peptide vials cool, dry and shielded from light, with longer-term storage under refrigeration or freezing according to internal protocols. Handling, reconstitution and storage decisions should follow the receiving laboratory's own written procedures and applicable safety guidance.

Can PE-22-28 be used outside a laboratory setting?

No. PE-22-28 is classified as a research chemical for in vitro and preclinical laboratory investigation only. It is not a drug, dietary supplement or cosmetic, is not approved for any therapeutic use, and is not intended to diagnose, treat, cure or prevent any condition in humans or animals.

PE-22-28 is a synthetic collagen-fragment peptide designed to jump-start extracellular-matrix and wound-closure pathways in cell cultures and animal models. Each 8 mg vial delivers a stable, ready-to-use peptide that accelerates fibroblast migration and boosts collagen-I synthesis—no extra growth factors required. HPLC-verified at ≥ 99% purity, and endotoxin-screened (< 0.1 EU/mg), PE-22-28 brings consistency and speed to your tissue-repair assays every time.

What Is PE-22-28 Peptide?

PE-22-28 is an eight-amino-acid fragment derived from collagen’s type I sequence. In the lab, it mimics collagen breakdown signals that naturally trigger fibroblast activation and matrix remodeling—making it a go-to reagent for studying wound-healing, skin regeneration, and extracellular-matrix dynamics.

Why Choose PE-22-28?

Choose PE-22-28 when you need a single, targeted peptide to model tissue repair without juggling multiple growth factors. Its direct action on fibroblasts and collagen pathways delivers reproducible wound-closure and ECM-synthesis data, so you can compare treatments, screen biomaterials, or optimize tissue-engineering protocols—all from one vial.

What Sets PE-22-28 Apart?

Unlike generic collagen hydrolysates, PE-22-28 offers precise sequence specificity and high receptor affinity, leading to faster fibroblast response and stronger collagen deposition. Its defined fragment length ensures consistent activity and easy integration into both 2D and 3D tissue-model systems.
