Description

Hepta-n-Acetylchitoheptaose is a defined, high-purity oligosaccharide derived from chitin, representing a heptamer of N-acetylglucosamine units. This compound serves as a critical biochemical tool and a reference standard for research into chitin metabolism, plant defense mechanisms, and innate immune responses. It is essential for scientists and manufacturers in the pharmaceutical, agricultural biotechnology, and life science research sectors who require precise molecular probes to study chitinase enzymes, pathogen recognition, and signal transduction pathways.

Application

• Biochemical Research: As a defined substrate for kinetic studies and inhibition assays of chitinase and lysozyme enzymes.
• Plant Science: Used to study plant innate immunity and defense signaling pathways triggered by chitin oligomers.
• Pharmaceutical Development: Serves as a reference standard and a potential starting material for developing immunomodulators or anti-inflammatory agents.
• Agricultural Biotechnology: Employed in research to develop novel plant protection strategies and bio-stimulants.
• Diagnostic Reagent Manufacturing: Used in the formulation of kits for detecting chitinase activity in clinical or environmental samples.
• Standards and Calibration: Acts as a high-purity calibrant for analytical methods like HPLC and mass spectrometry in carbohydrate analysis.
