Description

This tripeptide-copper(II) complex represents a key endogenous signaling molecule studied for its capacity to modulate gene expression across tissue repair, anti-inflammatory, and antioxidant pathways. The copper ion coordination provides both structural stability and bioactive metal delivery. For research use only.

ECM Remodeling & Collagen Synthesis: Investigated for upregulation of collagen I, III, and decorin expression via TGF-β pathway modulation and metalloproteinase activity regulation in dermal fibroblast models.
Antioxidant Gene Activation: Studied for Nrf2/ARE pathway engagement driving SOD, catalase, and glutathione peroxidase expression in oxidative stress research models.
Anti-Inflammatory Signaling: Explored for suppression of NF-κB-mediated IL-6 and TNF-α release and modulation of TGF-β superfamily signaling in tissue inflammation assays.

Always quality-tested, verified with third-party COAs

Every David & Merritt batch is independently screened for identity, purity, and endotoxins before it ever leaves our facility. No lot is released until it meets our research-grade threshold and clears third-party verification — documented in a COA that ships with every order.

The result is simple: no guesswork, no surprises — just material you can build your research on.

Identity Test

Passed

Verifies the peptide’s sequence and structure so the correct compound is present in each vial.

Purity Test

Passed

Measures purity and concentration to confirm ≥99% purity on qualifying batches.

Sterility Test

Passed

Screens for bacteria, fungi, and other microorganisms to verify sterile handling.

Endotoxicity

Passed

Tests for lipopolysaccharides (LPS) to ensure endotoxin levels stay within research limits.

Commonly asked Questions by Researchers

Everything you need to know before you order — batch verification, COA documentation, storage conditions, and handling guidelines, all in one place.

Each David & Merritt batch goes through HPLC and mass spectrometry analysis to confirm identity and purity — nothing ships until it clears our verification process.

Absolutely. Every product ships with a batch-specific COA that includes identity confirmation, purity data, and endotoxin results for full research traceability.

All peptides arrive as lyophilized powder in individually sealed vials, clearly labeled with the peptide name, lot number, and quantity.

We target ≥98% purity by HPLC across our entire catalog. The exact value for each batch is documented on the COA — no approximations.

Unopened vials should be kept sealed, away from light and humidity, and stored refrigerated or frozen per the guidelines listed on the COA.

Reconstituted peptides should be aliquoted and stored under refrigerated or frozen conditions to preserve stability and reduce the number of freeze–thaw cycles.

It depends on the peptide, but lyophilized vials stored correctly are stable long-term. Check the COA for batch-specific stability and expiry information.
