Description

Lactoferricin B (4-14) (Bovine) is a cationic antimicrobial peptide derived from the N-terminal region of bovine lactoferrin. This potent fragment is valued for its broad-spectrum activity against bacteria, fungi, and certain viruses, while also exhibiting immunomodulatory properties. It is a critical research and development component for pharmaceutical, nutraceutical, and personal care industries seeking natural bioactive ingredients for antimicrobial formulations and functional product development.

Application

• Antimicrobial Agent Development: Serves as a lead compound or active ingredient in the research and formulation of novel antibiotics and antifungal agents.
• Functional Food & Nutraceuticals: Incorporated into dietary supplements and functional foods for its potential immune-supporting and gut health-promoting benefits.
• Cosmeceutical & Personal Care: Used in skincare formulations such as creams, lotions, and serums for its antimicrobial and anti-inflammatory properties to address acne and skin health.
• Biomedical Research: A vital tool for studying host defense peptides, mechanisms of antimicrobial action, and structure-activity relationships (SAR).
• Veterinary Pharmaceuticals: Explored for use in animal health products to prevent or treat infections, leveraging its natural origin.
• Preservative Systems: Investigated as a natural preservative or shelf-life extender in various sensitive formulations where synthetic preservatives are undesirable.
