Description

Cysteine-Rich Intestinal Protein CAS NO 102857-11-4 is a specialized bioactive peptide with a high concentration of cysteine residues, playing a crucial role in intestinal health and metal ion homeostasis. Its significance lies in its potential as a research-grade biochemical for studying zinc and iron absorption pathways, as well as its application in developing nutritional and pharmaceutical formulations. This product is essential for research institutions, diagnostic manufacturers, and companies in the nutraceutical and biopharmaceutical sectors focused on gastrointestinal health and mineral metabolism.

Application

• Biochemical Research: Used as a key reagent in studies of intestinal zinc and iron transport mechanisms (e.g., ZIP4 transporter function).
• Diagnostic Development: Serves as a critical component or standard in immunoassays and test kits designed to detect biomarkers related to mineral deficiency or intestinal disorders.
• Nutraceutical Formulation: Incorporated into advanced dietary supplements aimed at supporting gut barrier integrity and enhancing mineral bioavailability.
• Pharmaceutical R&D: Investigated for its therapeutic potential in conditions like acrodermatitis enteropathica and other malabsorption syndromes.
• Cell Culture & In Vitro Studies: Utilized in media supplements or as a treatment to study cellular responses related to nutrient sensing and signaling in intestinal cell lines.
• Reference Standard: Acts as a high-purity calibrant or control material in analytical laboratories for protein quantification and characterization.

Quality Control

Our Cysteine-Rich Intestinal Protein is produced and tested under stringent quality management systems. Each batch undergoes rigorous analytical testing, including purity assessment by HPLC and identity confirmation, to ensure it meets high-purity research-grade standards. A comprehensive Certificate of Analysis (COA) detailing batch-specific results is provided with every shipment to guarantee traceability and compliance with your research or development requirements.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a desiccator before opening to prevent moisture uptake. For short-term use, store at 2-8°C.
