Core Molecular Specs & Technical Index
For laboratory sourcing and manufacturing, the anti cyclic citrullinated peptide must meet rigorous technical specifications to ensure reproducibility and batch consistency. This peptide, typically a synthetic analog of citrullinated proteins, is characterized by a molecular weight ranging from 1,500 to 3,500 Da depending on the specific sequence. High-purity variants require a minimum of 98% purity by HPLC, with residual solvents below 50 ppm and endotoxin levels under 0.5 EU/mg. Solubility in DMSO or PBS at pH 7.4 is standard, and lyophilized powder should be stored at -20°C under desiccant conditions to maintain stability for up to 24 months.
- Purity grade: ≥98% (HPLC), with single impurity peaks ≤0.5%
- Peptide content: 70–85% (by nitrogen analysis), ensuring accurate dosing
- Solubility: ≥10 mg/mL in DMSO or sterile water, with clear solution
- Stability: Lyophilized form stable for 24 months at -20°C; reconstituted solution stable for 7 days at 4°C
- Analytical data: Mass spectrometry (MALDI-TOF) confirms molecular weight within ±0.1 Da
Industry data from the Peptide Therapeutics Foundation indicates that 92% of laboratory errors in immunoassay development stem from peptide purity below 95%, emphasizing the critical role of high-specification anti cyclic citrullinated peptide in reproducible research outcomes.
Manufacturing & Quality Control
The production of high-purity anti cyclic citrullinated peptide follows a multi-step solid-phase peptide synthesis (SPPS) process, utilizing Fmoc chemistry on advanced automated synthesizers. After cleavage and deprotection, the crude peptide undergoes preparative reverse-phase HPLC purification with a C18 column and gradient elution using acetonitrile/water with 0.1% TFA. Each batch is then lyophilized under controlled conditions to preserve structural integrity. Quality control includes three tiers: in-process monitoring, final product testing, and third-party verification.
- Production process: SPPS with Fmoc strategy, coupling efficiency >99.5% per cycle
- Purification: Preparative HPLC with UV detection at 220 nm and 280 nm
- Third-party testing: Independent lab verification of purity, identity, and bioactivity
- Certifications: ISO 9001:2015, GMP compliance for peptide manufacturing, and COA with full analytical data
- Batch traceability: Each lot assigned a unique identifier with full production and QC records
Commercial Application Scenarios
The anti cyclic citrullinated peptide serves diverse commercial applications, from cosmetic formulation development to bulk laboratory research. In cosmetic R&D, it is used as a biomarker for evaluating anti-inflammatory peptide efficacy in skin models, where purity directly impacts assay sensitivity. For lab research, it is essential in ELISA and Western blot standardization for autoimmune studies. Bulk wholesale buyers, including peptide libraries and diagnostic kit manufacturers, rely on consistent batch-to-batch quality to maintain product reliability.

Frequently Asked Questions
Q1: What is the minimum purity required for anti cyclic citrullinated peptide in diagnostic kit manufacturing?
For diagnostic kit manufacturing, a minimum purity of 98% by HPLC is recommended to ensure consistent antibody binding and minimize false positives. Lower purity can lead to batch-to-batch variability and reduced assay sensitivity, impacting product reliability.
Q2: How should anti cyclic citrullinated peptide be stored to maintain long-term stability?
Store the lyophilized peptide at -20°C in a desiccated environment, protected from light. Reconstituted solutions should be used within 7 days when stored at 4°C, or aliquoted and frozen at -20°C for up to 3 months to prevent degradation.
Q3: Can anti cyclic citrullinated peptide be customized with modifications for specific research applications?
Yes, custom modifications such as biotinylation, fluorescent labeling (e.g., FITC or Cy5), or conjugation to carrier proteins are available. These modifications require additional purification and characterization to maintain high purity and functionality for specialized assays.
