Description

Glucuronoxylomannan is a high-molecular-weight polysaccharide, a key structural component derived from fungal cell walls. This biopolymer is valued for its unique rheological properties and biocompatibility, making it an essential functional ingredient in advanced formulations. It is primarily utilized by industries focused on pharmaceuticals, biomedical research, and high-value nutraceuticals where material consistency and biological activity are critical.

Application

• Pharmaceutical Excipient: Used as a stabilizer, viscosity enhancer, and controlled-release matrix in tablet and capsule formulations.
• Biomedical Research: Serves as a model compound for studying host-pathogen interactions, particularly in immunology and mycology research.
• Vaccine Adjuvant Development: Investigated for its immunomodulatory properties in the research and development of novel vaccine platforms.
• Nutraceutical & Functional Foods: Employed as a dietary fiber and prebiotic component in specialty health supplements.
• Cosmetic Formulations: Acts as a natural moisturizing and film-forming agent in high-end skincare products.
• Microencapsulation: Utilized for the encapsulation of sensitive bioactive compounds due to its film-forming ability.

Quality Control

Our Glucuronoxylomannan is produced and tested under strict quality management protocols. Each batch is characterized for key parameters including polysaccharide content, monosaccharide composition, and molecular weight distribution to ensure batch-to-batch consistency and biological relevance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and specific biological activity (where applicable) is provided with every shipment to support your research and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a low-humidity environment to prevent moisture absorption and degradation. For long-term storage, consider desiccants or inert atmosphere.
