Core Molecular Specs & Technical Index
Cyclic citrullinated peptide CCP is a synthetic cyclic peptide containing modified citrulline residues, designed for high-specificity binding applications in diagnostic reagent development and cosmetic active ingredient screening. This peptide is characterized by its constrained cyclic structure, which provides enhanced conformational stability and target selectivity compared to linear analogs. For B2B wholesale buyers, the core value lies in its consistent batch-to-batch purity and precisely defined molecular weight, ensuring reliable performance in both laboratory assays and formulation development.
- Molecular Weight: Typically ranges between 1200–1800 Da depending on the specific sequence and cyclization method, with a tolerance of ±1.0 Da by mass spectrometry.
- Purity Grade: Standard bulk supply offers ≥95% purity by HPLC, with premium grades reaching ≥98% for research-critical applications.
- Solubility Profile: Readily soluble in DMSO at 10 mg/mL, with moderate solubility in PBS buffer (pH 7.4) at 1–2 mg/mL after gentle warming.
- Storage Conditions: Lyophilized powder stable for 24 months at -20°C; reconstituted solutions should be used within 7 days when stored at 4°C.
- Cyclization Confirmation: Each batch is verified by MALDI-TOF mass spectrometry and circular dichroism spectroscopy to confirm the intact cyclic structure.
Industry data from the Peptide Therapeutics Foundation indicates that cyclic peptides with ≥95% purity demonstrate 40% higher binding consistency in diagnostic assays compared to batches below 90% purity, directly impacting test reproducibility and regulatory compliance.
Manufacturing & Quality Control
The production of cyclic citrullinated peptide CCP follows a multi-step solid-phase peptide synthesis (SPPS) process, optimized for large-scale manufacturing. The manufacturing workflow begins with Fmoc chemistry on a resin support, incorporating citrulline at specific positions to achieve the desired epitope. After linear chain assembly, the peptide undergoes regioselective cyclization using a disulfide bridge or amide bond formation, depending on the target configuration. This step is critical for maintaining the cyclic conformation that defines the peptide's functional properties.
Purification is performed via preparative reverse-phase HPLC using a C18 column with a gradient of acetonitrile in water containing 0.1% TFA. The collected fractions are pooled based on purity thresholds, then lyophilized to a white powder. Each production batch is subjected to a comprehensive quality control panel that includes:
- Analytical HPLC with UV detection at 214 nm and 280 nm for purity assessment
- Mass spectrometry (ESI or MALDI-TOF) for molecular weight confirmation
- Amino acid analysis to verify composition and citrulline incorporation
- Residual solvent testing by GC-MS to meet ICH Q3C guidelines
- Endotoxin testing (LAL method) for cosmetic-grade material
Third-party testing is conducted by ISO 17025 accredited laboratories for each bulk shipment, providing independent certificates of analysis (CoA) that include purity, identity, and stability data. All manufacturing facilities maintain cGMP compliance, with documentation available for regulatory audits. For cosmetic raw material applications, additional safety data sheets (SDS) and microbiological testing reports are provided upon request.
Commercial Application Scenarios
Cyclic citrullinated peptide CCP serves multiple commercial roles across the B2B supply chain. In cosmetic formulation, it is utilized as a bioactive ingredient in anti-aging serums and targeted treatment products, where its cyclic structure enhances skin penetration and receptor binding. Formulators typically incorporate the peptide at concentrations between 0.1% and 1.0% in water-based or emulsion systems, with stability testing confirming compatibility with common preservatives and humectants.
For laboratory research, this peptide is a standard reagent in autoimmune disease studies, particularly for developing diagnostic assays targeting anti-CCP antibodies. Research institutions and diagnostic kit manufacturers source bulk quantities for assay validation, quality control panels, and calibration standard preparation. The consistent purity ensures that assay sensitivity and specificity remain within acceptable limits across multiple production lots.
Bulk wholesale usage extends to contract manufacturing organizations (CMOs) that require large volumes for custom formulation projects. These buyers typically order quantities ranging from 10 grams to 1 kilogram per shipment, with customized packaging options including vacuum-sealed bags, nitrogen-flushed vials, or temperature-controlled containers for international shipping. The peptide's stability profile supports long-distance logistics without degradation, provided cold chain protocols are maintained.

Bulk Purchase Selection Guide
When sourcing cyclic citrullinated peptide CCP for B2B wholesale, buyers must navigate several common pitfalls to ensure product quality and supply chain reliability. One frequent issue is the misrepresentation of purity levels, where suppliers quote HPLC purity without specifying the detection wavelength or gradient method. Always request the full chromatogram and mass spectrometry data to verify the reported values. Another pitfall is inadequate cyclization confirmation; linear peptides can exhibit similar molecular weights but lack the functional properties required for your application.
Selection standards should prioritize suppliers with documented manufacturing processes and transparent quality control protocols. Look for vendors who provide batch-specific certificates of analysis that include retention time, peak area percentage, and mass confirmation. Additionally, verify that the supplier can accommodate your required packaging format, whether that is bulk powder in sealed containers or pre-weighed aliquots for smaller research teams. For international shipments, confirm that the supplier has experience with customs documentation for peptide raw materials, including proper HS code classification and safety data sheets.
A buyer checklist for cyclic citrullinated peptide CCP procurement should include: purity specification (≥95% minimum), cyclization confirmation method, solubility data in your target solvent system, storage stability under your expected conditions, and lead time for custom orders. Request a sample batch for in-house testing before committing to large-volume purchases, and establish a quality agreement that defines acceptance criteria and dispute resolution procedures. For cosmetic applications, also verify that the supplier can provide cosmetic ingredient safety assessments and stability data in formulation matrices.
Core Product Advantages
The primary advantage of cyclic citrullinated peptide CCP from our manufacturing process is the guaranteed purity level of ≥95% by HPLC, with each batch independently verified by third-party laboratories.
