Target Keyword: what is glucagon like peptide 1
Core Molecular Specs & Technical Index
Glucagon-like peptide-1 (GLP-1) is a 30-31 amino acid incretin hormone produced in the intestinal L-cells. It plays a fundamental role in glucose metabolism by stimulating insulin secretion in a glucose-dependent manner. For B2B buyers in the cosmetic and lab raw material sectors, understanding the precise molecular specifications is critical for formulation success and research reproducibility. The peptide is typically supplied as a lyophilized powder with a molecular weight of approximately 3298.7 Da for the active fragment (7-36 amide).
- Purity Standard: Minimum 98% purity verified by HPLC analysis, with endotoxin levels below 1 EU/mg for research-grade applications.
- Solubility Profile: Readily soluble in water at 1 mg/mL, with optimal reconstitution in sterile PBS or acetic acid solution for maximum stability.
- Storage Requirements: Lyophilized powder stable for 24 months at -20°C; reconstituted solution must be used within 7 days when stored at 4°C.
- Sequence Integrity: Full-length GLP-1 (7-36) amide sequence confirmed by mass spectrometry and amino acid analysis.
- Biological Activity: EC50 value below 5 nM in cAMP accumulation assays using GLP-1 receptor-expressing cell lines.
Industry data indicates that the global GLP-1 receptor agonist market reached $28.5 billion in 2023, with a compound annual growth rate (CAGR) of 12.8% projected through 2030. This growth is primarily driven by expanding applications in metabolic research and cosmetic dermatology formulations.
Manufacturing & Quality Control
The production of high-purity GLP-1 peptide involves solid-phase peptide synthesis (SPPS) using Fmoc chemistry on advanced automated synthesizers. This process ensures precise amino acid coupling with minimal racemization. Following synthesis, the crude peptide undergoes cleavage from the resin and global deprotection. Purification is achieved through preparative reverse-phase HPLC using C18 columns with gradient elution systems. Each batch is subjected to rigorous quality control protocols including analytical HPLC for purity assessment, mass spectrometry for molecular weight confirmation, and amino acid analysis for composition verification. Third-party testing by ISO 17025 accredited laboratories provides independent validation of product specifications. Certifications commonly required by B2B buyers include Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS), and stability study reports. For cosmetic applications, additional testing for heavy metals, microbial limits, and residual solvents is mandatory. The entire manufacturing process follows Good Manufacturing Practice (GMP) guidelines to ensure batch-to-batch consistency and traceability.
Commercial Application Scenarios
In cosmetic formulation, GLP-1 peptide is increasingly incorporated into anti-aging serums and topical treatments targeting skin metabolism and cellular renewal. Research-grade GLP-1 is essential for laboratory studies investigating receptor signaling pathways and metabolic regulation. Bulk wholesale customers typically require kilogram quantities for large-scale research programs or commercial product development. Common usage scenarios include: formulation of peptide-based cosmetic creams at concentrations of 0.1-1.0%, preparation of stock solutions for in vitro cell culture experiments at 10-100 µM, and development of novel drug delivery systems for transdermal applications. The peptide's stability in various formulation matrices, including oil-in-water emulsions and hydrogel systems, makes it versatile for multiple product types. B2B buyers should verify compatibility with their specific formulation excipients through preliminary stability testing.

Bulk Purchase Selection Guide
When sourcing GLP-1 peptide for commercial or research purposes, B2B buyers must avoid common pitfalls that compromise product quality and project outcomes. The most frequent issues include purchasing peptides with insufficient purity for specific applications, improper storage leading to degradation, and lack of proper documentation for regulatory submissions. Selection standards should prioritize suppliers who provide comprehensive analytical data including HPLC chromatograms, mass spectra, and stability profiles. A buyer checklist should include verification of manufacturing facility GMP certification, confirmation of third-party testing protocols, and assessment of supply chain reliability for consistent bulk deliveries. Additionally, buyers should request samples for in-house validation before committing to large orders. Understanding the peptide's solubility characteristics and compatibility with intended formulation systems is essential for successful product development. Price comparison should consider total cost including shipping, customs clearance, and potential quality control expenses.

Frequently Asked Questions
Q: What is the recommended storage condition for reconstituted GLP-1 peptide?
A: Reconstituted GLP-1 peptide should be stored at 4°C and used within 7 days. For longer storage, aliquot and freeze at -20°C for up to 30 days. Avoid repeated freeze-thaw cycles to maintain peptide integrity.
Q: How does GLP-1 purity affect cosmetic formulation performance?
A: Higher purity (≥98%) ensures consistent biological activity and reduces the risk of skin irritation from impurities. Lower purity peptides may contain truncated sequences or byproducts that compromise formulation stability and efficacy.
Q: What documentation is required for regulatory submission of GLP-1 peptide products?
A: Essential documents include Certificate of Analysis (CoA) with HPLC and mass spectrometry data, Material Safety Data Sheet (MSDS), stability study reports, and GMP manufacturing certificates. Additional toxicology reports may be required for cosmetic applications.
