Core Molecular Specs & Technical Index
Cyclic citrullinated peptide antibody is a chemically synthesized cyclic peptide containing citrulline residues, designed for high-affinity binding in immunoassays. The following technical parameters define its suitability for professional laboratory use.
- Molecular Weight: Typically ranges between 1,500–3,000 Da, depending on the specific cyclic structure and citrullination pattern.
- Purity Grade: Minimum 95% by HPLC, with premium grades offering ≥98% for research-critical applications.
- Solubility: Fully soluble in DMSO or PBS (pH 7.4) at concentrations up to 10 mg/mL without aggregation.
- Storage Stability: Lyophilized powder stable for 24 months at -20°C; reconstituted solutions stable for 7 days at 4°C.
- Batch Consistency: Each lot tested for peptide content, sequence confirmation via mass spectrometry, and endotoxin levels below 1 EU/mg.
Industry data from 2023 indicates that 78% of diagnostic kit manufacturers require cyclic citrullinated peptide antibody purity above 97% to achieve <0.05 AU/mL detection limits in rheumatoid arthritis assays.
Manufacturing & Quality Control
Production of cyclic citrullinated peptide antibody follows a rigorous multi-step process to ensure batch-to-batch reproducibility and functional integrity. Quality control protocols are aligned with ISO 13485 and GMP guidelines for raw material suppliers.
Production Process
Solid-phase peptide synthesis (SPPS) is employed using Fmoc chemistry, with selective citrullination at defined positions. Cyclization is achieved via disulfide bridge formation or amide bond closure, followed by preparative HPLC purification.
Purification & Verification
Reverse-phase HPLC with C18 columns removes truncated sequences and side products. Each batch undergoes MALDI-TOF mass spectrometry for molecular weight confirmation and amino acid analysis for composition accuracy.
Third-Party Testing
Independent laboratories verify purity, solubility, and binding activity using ELISA against standardized anti-CCP positive sera. Certificates of analysis (CoA) include HPLC chromatograms, MS spectra, and endotoxin reports.
- ISO 9001:2015 certified manufacturing facility
- GMP-compliant cleanroom environment (Class 10,000)
- Batch-specific CoA with full analytical data
- Stability studies per ICH Q1A guidelines
- Custom synthesis available for modified sequences
Commercial Application Scenarios
Cyclic citrullinated peptide antibody serves diverse B2B applications, from cosmetic ingredient testing to high-throughput diagnostic production. Understanding these use cases helps buyers select appropriate purity grades and volumes.
Cosmetic Formulation Research
In cosmetic labs, cyclic citrullinated peptide antibody is used as a positive control in skin irritation and autoimmune response assays. Purity of 95% suffices for screening purposes, with bulk orders of 10–50 mg per project.
Laboratory Research & Assay Development
Academic and contract research organizations (CROs) require ≥98% purity for developing novel ELISA kits or lateral flow devices. Typical order sizes range from 5 mg to 100 mg for validation studies.
Bulk Wholesale for Diagnostic Manufacturing
Diagnostic companies purchase cyclic citrullinated peptide antibody in gram quantities for commercial kit production. Purity ≥97% and endotoxin control are mandatory, with annual contracts often exceeding 10 grams.

Bulk Purchase Selection Guide
Procuring cyclic citrullinated peptide antibody in bulk requires careful evaluation of supplier capabilities and product specifications. Below are common pitfalls and a buyer checklist to ensure quality and cost-effectiveness.
Common Pitfalls
Many buyers overlook endotoxin testing for cell-based applications, leading to failed experiments. Additionally, low-purity peptides cause non-specific binding in ELISA, wasting reagents and time. Always request a CoA before ordering.
Selection Standards
Prioritize suppliers with ISO certification and published stability data. For diagnostic use, demand HPLC purity ≥97% and mass spectrometry confirmation. Cosmetic labs may accept 95% purity but should verify solubility in relevant buffers.
Buyer Checklist
- Request batch-specific CoA with HPLC and MS data
- Confirm endotoxin levels for cell-based assays
- Verify storage conditions and shelf life
- Ask about custom synthesis capabilities
- Compare pricing per milligram at different purity grades
