PE-22-28 (8mg)

Q: What is PE-22-28 peptide used for?

To study wound closure, collagen-I synthesis, and ECM remodeling in cell and animal models.

Q: How does PE-22-28 accelerate wound healing?

By triggering fibroblast migration and collagen-I production via TGF-β/SMAD signaling.

Q: What concentration is typical in vitro?

Researchers often use 1–10 µg/mL, adjusted per cell type and assay design.

Q: Can PE-22-28 improve ECM organization?

Yes—it enhances collagen fibril alignment in 3D constructs and tissue explants.

Q: How quickly does it act in scratch assays?

Increased fibroblast migration is seen within 6–12 hours, speeding closure readouts.

Q: How do I prepare PE-22-28 peptide?

Reconstitute in Sterile Water for Injection, gently mix, then use immediately or store at 2–8 °C.

Q: What storage conditions are required?

Store powder at –20 °C; use reconstituted solution within 7 days at 2–8 °C.

Q: Does PE-22-28 affect other pathways?

Its design minimizes off-target effects, focusing on collagen and fibroblast signaling.

Q: Is PE-22-28 approved for clinical use?

No—strictly for research use only, not for therapeutic or veterinary applications.

Q: Is a certificate of analysis available for PE-22-28?

Yes. Every Real Peptides batch is third-party lab tested and its certificate of analysis is published on the site, searchable by product name or SKU.

AboutSpecificationsQuestions

Finished in the USA

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.
