Description

Lacticin 481 is a Class II bacteriocin produced by certain strains of lactic acid bacteria. This compound is valued for its potent and narrow-spectrum antimicrobial activity, primarily against other Gram-positive bacteria. It is a critical tool for research and development in food preservation, probiotics, and antimicrobial discovery. Industrial users in the biotechnology, food science, and pharmaceutical sectors rely on its specific mode of action for targeted applications.

Application

• Research and development of novel food biopreservatives and natural antimicrobials.
• Studying bacteriocin structure, function, and mode of action in academic and industrial laboratories.
• Development of starter cultures and probiotics with enhanced protective properties for fermented foods.
• Investigation of synergistic effects with other antimicrobials or preservation techniques (hurdle technology).
• Model compound for studying gene regulation and production of lantibiotics.
• Potential applications in veterinary or medical research targeting specific Gram-positive pathogens.

Quality Control

Our Lacticin 481 is produced and handled under strict quality protocols to ensure batch-to-batch consistency and biological activity. Each lot is accompanied by comprehensive documentation, including a Certificate of Analysis (COA) detailing purity, potency (activity units), and relevant analytical data. We support research-grade standards and can provide material tailored to specific project requirements upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This material is hygroscopic (moisture-sensitive); allow the sealed container to equilibrate to room temperature before opening to prevent condensation. For extended storage under inert atmosphere, please contact our technical team for specific recommendations.
