Description

Nigeran Tetrasaccharide From*Aspergillus Japonicus is a defined oligosaccharide derived from the enzymatic hydrolysis of nigeran, a fungal polysaccharide. This high-purity reference standard is critical for research and development in carbohydrate chemistry and enzymology. It is primarily utilized by scientists and manufacturers in the pharmaceutical, biotechnology, and analytical reagent sectors for method development, calibration, and biochemical studies.

Application

• Biochemical Research: As a defined substrate or standard for studying the activity, specificity, and kinetics of glycosyl hydrolases, particularly α-amylases and related enzymes.
• Pharmaceutical Development: Used in the research of carbohydrate-based drugs, vaccine adjuvants, and diagnostic agents where specific oligosaccharide structures are required.
• Analytical Reference Standard: Serves as a high-purity calibrant in chromatographic (HPLC, HPAEC-PAD) and spectroscopic methods for carbohydrate analysis and quantification.
• Enzyme Production & Quality Control: Employed in the fermentation process development and potency assay of industrial enzymes derived from *Aspergillus* and other fungal species.
• Food Science Research: Applied in studies investigating starch degradation, dietary fiber analysis, and the functional properties of oligosaccharides.
