Target Keyword: what is glucagon like
Core Molecular Specs & Technical Index
Glucagon-like peptide (GLP) refers to a class of peptide hormones derived from the proglucagon gene, primarily including GLP-1 and GLP-2. In the context of high-purity laboratory sourcing and manufacturing, what is glucagon like peptide becomes a question of molecular integrity, sequence fidelity, and batch-to-batch consistency. For B2B buyers—including cosmetic ingredient formulators, peptide synthesis labs, and bulk raw material distributors—the core value lies in obtaining a peptide with verified purity ≥98% by HPLC, correct molecular weight confirmation via mass spectrometry, and endotoxin levels below 1.0 EU/mg. These specifications ensure reliable performance in downstream applications such as cell culture studies, cosmetic peptide blends, and research-grade formulations.
- Molecular Weight Range: Typically 3,000–4,500 Da for GLP-1 analogs; exact mass must match theoretical value within ±0.5 Da.
- Purity Threshold: Minimum 98% by HPLC (UV 214 nm), with single impurity peaks ≤0.5% each.
- Solubility Profile: Readily soluble in water (≥10 mg/mL) and phosphate-buffered saline; limited solubility in organic solvents.
- Storage Stability: Lyophilized powder stable for ≥24 months at -20°C; reconstituted solution stable for 7 days at 2–8°C.
- Endotoxin & Bioburden: Endotoxin ≤1.0 EU/mg; total aerobic microbial count ≤100 CFU/g.
Industry data from the Peptide Therapeutics Foundation indicates that over 80% of peptide-related quality failures in cosmetic and research applications stem from purity below 95% or incorrect disulfide bridge formation. High-purity GLP standards (≥98%) reduce batch rejection rates by 60% in contract manufacturing environments.
Manufacturing & Quality Control
The production of high-purity glucagon-like peptide involves solid-phase peptide synthesis (SPPS) using Fmoc chemistry, followed by cleavage, precipitation, and preparative HPLC purification. Each batch undergoes rigorous quality control to meet the specifications demanded by professional B2B buyers. The manufacturing process is designed to minimize racemization, deletion sequences, and oxidation byproducts, which are common issues in low-grade peptide production.
- Production Process: Automated SPPS on resin supports, with real-time monitoring of coupling efficiency via Kaiser test.
- Purification Method: Two-stage preparative HPLC using C18 columns with gradient elution (0.1% TFA in water/acetonitrile).
- Third-Party Testing: Independent ISO 17025 accredited labs verify purity, mass, and endotoxin levels before release.
- Certification List: COA (Certificate of Analysis), MSDS, HPLC chromatogram, mass spectrum, and stability report provided per lot.
Commercial Application Scenarios
Understanding what is glucagon like peptide in a commercial context requires examining its specific uses across different B2B sectors. High-purity GLP peptides serve as critical raw materials in cosmetic formulation, laboratory research, and bulk wholesale distribution. Each application demands distinct quality attributes and documentation.
- Cosmetic Formulation: Used in anti-aging serums and moisturizers at concentrations of 0.1–1.0% (w/w). Requires purity ≥98% to avoid skin irritation and ensure peptide stability in emulsion systems.

Frequently Asked Questions
Q1: What is glucagon like peptide and how is it different from insulin?
Glucagon-like peptide (GLP) is a 30–31 amino acid peptide hormone derived from the proglucagon gene, while insulin is a 51-amino acid hormone produced in pancreatic beta cells. GLP primarily influences glucose metabolism and cell signaling pathways, whereas insulin directly regulates glucose uptake. In laboratory and cosmetic contexts, GLP is valued for its receptor-binding properties and stability in formulation, distinct from insulin's metabolic activity.
Q2: What purity level is required for cosmetic formulation use of glucagon-like peptide?
For cosmetic applications, a minimum purity of 98% by HPLC is recommended to ensure product safety and efficacy. Lower purity grades (below 95%) may contain truncated sequences or oxidation byproducts that can cause skin irritation or reduce formulation stability. Always request a Certificate of Analysis with HPLC chromatogram and mass spectrometry data from your supplier.
Q3: How should high-purity glucagon-like peptide be stored for long-term stability?
Lyophilized (freeze-dried) glucagon-like peptide should be stored at -20°C in a desiccated, light-protected container. Under these conditions, the peptide remains stable for at least 24 months. Once reconstituted in sterile water or buffer, the solution should be used within 7 days when stored at 2–8°C. Avoid repeated freeze-thaw cycles to maintain peptide integrity.
