🔬 Research Applications (For In Vitro / Preclinical Use Only)

GHK-Cu (Copper Tripeptide-1, CAS No. 49557-75-7) is a naturally occurring copper-binding peptide formed by the combination of glycyl-histidyl-lysine tripeptide with copper ions. As a small-molecule bioactive peptide, it has been widely studied in cosmetic science, tissue engineering, molecular biology and other fields. Our GHK-Cu is produced in strict accordance with GMP standards, with high purity and stable batch consistency, making it an ideal raw material for in vitro laboratory research and cosmetic formulation development.

Core Advantages

Ultra-High Purity & Strict Quality Control

Each batch of GHK-Cu is tested by HPLC, LC-MS and elemental analysis to ensure accurate composition and qualified purity.

A complete COA is provided with each order, including chromatograms, mass spectrometry data, endotoxin test results and other complete documents.

Strict quality control procedures ensure batch consistency, minimize experimental errors, and meet high-precision research requirements.

GMP Standard Production Environment

Products are manufactured in a GMP-compliant clean workshop with Class 100,000 cleanroom standard.

Raw materials are sourced from qualified suppliers and undergo strict incoming inspection to ensure product quality from the source.

The entire production process is fully traceable, with complete records from raw material receipt to finished product delivery, in line with international research raw material management requirements.

Stable Formulation & Convenient Use

Lyophilized powder form ensures stronger stability, less degradation, and convenient long-term storage and transportation.

The product is soluble in water and physiological saline, compatible with various in vitro experimental systems, with high dissolution efficiency and simple operation.

Multiple packaging specifications (10mg, 50mg, 100mg, 1g) are available to meet the needs of small-scale trials and bulk procurement.

Factory Direct Supply with High Cost Performance

Direct shipment from the source factory with no middleman markup, providing a more competitive price.

Flexible MOQ is supported, allowing both small-batch trial orders and large-volume customized orders.

Fast global shipping with neutral and discreet packaging to ensure cargo safety and improve customs clearance efficiency.

Scientific Research Application Fields

Cosmetic Science Research

For research on mechanisms related to skin barrier, skin aging and skin damage repair.

For experiments on stability and efficacy evaluation of topical formulations.

For research on mechanisms related to extracellular matrix and collagen metabolism.

Tissue Engineering and Regenerative Medicine Research

For in vitro experiments related to cell behavior and research on cell model construction.

For research on vascular-related tissue models and inflammation-related tissue models.

For research and development of biological scaffold materials for tissue repair.

Molecular Biology Research

For research on signal transduction pathways related to peptide-copper ion interactions.

For research on gene expression regulation related to tissue repair and antioxidant responses.

Handling and Storage Instructions

Reconstitution Method

Dissolve the lyophilized powder with sterile water or physiological saline to the desired concentration and shake gently.

For long-term storage, aliquot into small volumes to avoid repeated freezing and thawing, and store at -20°C.

Avoid exposure to light, high temperature and humid environments during reconstitution and use.

ECHEMI Editorial Reference

Long arginine 3-IGF-1, abbreviated as IGF-1 LR3 or LR3-IGF-1, is a synthetic protein and lengthened analogue of human insulin-like growth factor 1 (IGF-1). It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence ("arginine 3"), and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN) ("long"), for a total of 83 amino acids (relative to the 70 of IGF-1).
