Description

Royalisin CAS NO 128906-89-8 is a specialized antimicrobial peptide, also known as a bacteriocin, with significant commercial and research interest. Its primary value lies in its potent and targeted antibacterial activity, particularly against Gram-positive bacteria, including *Listeria* species. This makes it a critical component for industries focused on food safety, biopreservation, and pharmaceutical development. Key users include manufacturers of functional foods, research institutions developing novel antimicrobial agents, and companies in the nutraceutical and cosmetic sectors seeking natural preservative solutions.

Application

• Food Biopreservative: Used to inhibit spoilage and pathogenic bacteria like *Listeria monocytogenes* in dairy products, meats, and ready-to-eat foods, extending shelf life naturally.
• Pharmaceutical Research: Serves as a lead compound or active ingredient in the development of new antimicrobial drugs and therapeutic peptides.
• Cosmetic Preservation: Incorporated into personal care formulations as a natural and effective preservative against microbial contamination.
• Nutraceutical Additive: Enhances the stability and safety of probiotic and dietary supplement products by controlling unwanted microbial growth.
• Veterinary Applications: Employed in animal feed or topical treatments to promote animal health and prevent bacterial infections.
• Agricultural Biocontrol: Explored for use in protecting crops from bacterial diseases as part of integrated pest management strategies.
• Diagnostic Reagent: Utilized in microbiological assays and test kits as a selective agent for bacterial identification and study.
• Biotechnology Tool: Applied in molecular biology and microbiology research to study bacteriocin mechanisms, gene expression, and host-pathogen interactions.

Quality Control

Our Royalisin is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high biological activity. Quality is verified through a comprehensive suite of analytical methods, including HPLC for purity assessment, mass spectrometry (MS) for identity confirmation, and microbiological assays for potency. A detailed Certificate of Analysis (COA), providing full specifications and test results, is supplied with each batch to support your quality assurance and regulatory compliance needs.

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 condensation and moisture uptake. For extended storage, consider under an inert atmosphere.
