Core Molecular Specs & Technical Index
Calcitonin Gene-Related Peptide (CGRP) is a 37-amino acid neuropeptide that plays a critical role in vasodilation and neurogenic inflammation. For B2B buyers in cosmetic formulation and laboratory research, sourcing cgrp with verified high purity is essential for reproducible results and regulatory compliance. Our product is manufactured under strict GMP guidelines to ensure batch-to-batch consistency.
- Molecular Weight: 3789.4 Da, confirmed by mass spectrometry (MS) analysis.
- Purity Grade: ≥98% by HPLC, with ≤1% individual impurity threshold.
- Solubility: Fully soluble in water and PBS buffer at 1 mg/mL concentration.
- Storage Stability: Lyophilized powder stable for 24 months at -20°C; reconstituted solution stable for 7 days at 4°C.
- Appearance: White to off-white lyophilized powder, free of visible particulates.
Industry data from the Peptide Therapeutics Foundation (2023) indicates that 87% of cosmetic peptide failures are linked to sub-98% purity, underscoring the need for rigorous quality control in cgrp supply chains.
Manufacturing & Quality Control
Our cgrp peptide is produced using solid-phase peptide synthesis (SPPS) on automated synthesizers, followed by cleavage and deprotection under controlled conditions. The crude peptide undergoes preparative HPLC purification to achieve the target purity level. Each batch is lyophilized and sealed under inert gas to prevent oxidation.
Quality control includes three independent tests: HPLC for purity, MS for molecular weight confirmation, and amino acid analysis for sequence verification. Third-party testing is conducted by an ISO 17025 accredited laboratory, with certificates of analysis (COA) provided for every lot.
- GMP Certification: Manufacturing facility complies with EU GMP and FDA 21 CFR Part 211 standards.
- Heavy Metal Testing: Meets USP <232> limits for elemental impurities.
- Endotoxin Level: ≤0.5 EU/mg, suitable for cosmetic and research applications.
- Bioburden Testing: Aerobic microbial count <100 CFU/g, no pathogens detected.
- Stability Data: Accelerated stability studies confirm 24-month shelf life at recommended storage conditions.
Commercial Application Scenarios
In cosmetic formulation, cgrp is utilized as a bioactive ingredient in anti-aging serums and creams, where its vasodilatory properties support improved microcirculation and skin radiance. Formulators typically incorporate it at concentrations between 0.1% and 0.5% in water-based systems.
For laboratory research, cgrp is employed in neuropeptide signaling studies, inflammation models, and vascular biology experiments. Bulk supply ensures consistent material for multi-replicate assays and long-term projects.
Wholesale buyers in the peptide distribution sector benefit from our bulk packaging options, ranging from 1 gram to 100 grams, with custom labeling and documentation for international shipping. Our logistics team ensures cold-chain delivery for temperature-sensitive orders.
cgrp VS Ordinary Low-Grade Peptides
| Item | Our Product | Alternatives | Advantages |
|---|---|---|---|
| Purity | ≥98% by HPLC | 85-92% by HPLC | Higher purity reduces side reactions |
| Endotoxin | ≤0.5 EU/mg | 1-5 EU/mg | Safer for cosmetic use |
| Stability | 24 months at -20°C | 6-12 months at -20°C | Longer shelf life reduces waste |
| Certification | GMP, COA, MS, HPLC | Basic COA only | Full traceability for audits |
Bulk Purchase Selection Guide
When sourcing cgrp in bulk, buyers often encounter pitfalls such as mislabeled purity, missing documentation, or inadequate packaging. To avoid these issues, follow this selection checklist:
- Request a Certificate of Analysis (COA): Verify HPLC chromatogram, MS spectrum, and amino acid analysis for each batch.
- Check GMP Certification: Ensure the manufacturer provides a valid GMP certificate from a recognized authority.
- Evaluate Packaging: Lyophilized powder should be in amber glass vials with desiccant and inert gas overlay.
- Confirm Shipping Conditions: For international orders, require cold-chain shipping with temperature data loggers.
- Review Stability Data: Ask for accelerated and real-time stability studies to confirm shelf life claims.
Our team provides free sample testing for qualified buyers, allowing you to evaluate product quality before committing to large volumes. We also offer custom peptide synthesis for modified sequences or specific purity requirements.
Core Product Advantages
Our cgrp peptide stands out in the market due to three key advantages: purity, stability, and cost performance. With ≥98% purity, you minimize batch variability and ensure consistent formulation results. The 24-month stability at -20°C reduces inventory management challenges and product waste.
Cost performance is achieved through efficient manufacturing processes and direct-to-buyer sales, eliminating intermediary markups. We offer volume discounts for orders above 10 grams, with additional savings for long-term supply agreements.
Technical support is provided by our in-house peptide chemists, who can assist with formulation advice, solubility optimization, and regulatory documentation. This ensures that your team can integrate cgrp into your products with confidence and speed.
Frequently Asked Questions
Q: What is the minimum purity required for cosmetic formulation use of cgrp?
A: For cosmetic applications, we recommend ≥98% purity to ensure product safety and efficacy. Lower purity levels may introduce impurities that could cause skin irritation or reduce formulation stability. Our standard product meets this threshold with full documentation.
Q: How should cgrp be stored after reconstitution?
A: After reconstitution in sterile water or PBS, cgrp should be stored at 4°C and used within 7 days. For longer storage, aliquot and freeze at -20°C for up to 3 months. Avoid repeated freeze-thaw cycles to maintain peptide integrity.
Q: Can you provide custom packaging for bulk cgrp orders?
A: Yes, we offer custom packaging options including bulk containers, individual vials, and custom labeling with your company logo and product information. Minimum order quantities apply for custom packaging. Contact our sales team for specific requirements.
