Description

Chitooctaose 8Hcl is a defined, high-purity oligosaccharide derived from chitosan, specifically an octamer of glucosamine hydrochloride. This compound matters as a critical research-grade biochemical tool for studying chitinase and chitosanase enzyme activity, as well as for investigating the structure-activity relationships of chitin derivatives. It is primarily needed by researchers in the life sciences, pharmaceutical development, and agricultural biotechnology sectors for use as a standard, substrate, or bioactive agent.

Application

• Enzyme Substrate: Used as a specific substrate for the assay and kinetic study of chitinases, chitosanases, and lysozymes.
• Biomedical Research: Investigated for its potential immunomodulatory, antimicrobial, and wound-healing properties in preclinical studies.
• Plant Elicitor: Applied in agricultural research to study plant defense mechanism activation and induced systemic resistance.
• Standard Reference Material: Serves as a high-purity chromatographic or spectroscopic standard for analytical method development and quality control of chitosan oligomers.
• Drug Delivery Research: Explored as a biocompatible carrier or functional component in novel drug delivery system formulations.
• Cosmeceutical Studies: Evaluated for potential applications in advanced skincare formulations due to its bioactive properties.
