Description

C-Reactive Protein (201-206) CAS NO 130348-99-1 is a defined synthetic peptide fragment corresponding to a specific region of the human C-reactive protein (CRP). This high-purity reference material is critical for research and diagnostic development, enabling precise study of protein interactions and immune response mechanisms. It is primarily utilized by biotechnology firms, pharmaceutical R&D departments, and clinical diagnostic manufacturers for applications in immunology, biomarker discovery, and assay calibration.

Application

• Immunoassay Development & Calibration: Serves as a critical reference standard and calibrator for developing and validating ELISA and other immunoassays targeting CRP.
• Antibody Production & Characterization: Used as an immunogen for generating specific monoclonal or polyclonal antibodies against the CRP (201-206) epitope.
• Biomarker Research: A key tool for investigating the role of specific CRP domains in cardiovascular disease, chronic inflammation, and other pathological conditions.
• Pharmaceutical Screening: Employed in high-throughput screening (HTS) assays to identify potential therapeutic compounds that modulate CRP-related inflammatory pathways.
• Quality Control in Diagnostics: Acts as a positive control and system suitability check for in-vitro diagnostic (IVD) kits and reagents.
• Structural & Functional Studies: Facilitates research into protein-protein interactions, receptor binding studies, and structural analysis of CRP.

Quality Control

Our C-Reactive Protein (201-206) is manufactured under strict quality systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and mass spectrometry (MS) for identity confirmation, to ensure it meets exacting standards for research and diagnostic use. Certificates of Analysis (COA) detailing purity, peptide content, and analytical data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature in a desiccator before opening to prevent condensation and moisture uptake. For long-term storage, keep desiccated.
