Description

Glycogen CAS NO 9005-79-2 is a highly branched polysaccharide of glucose that serves as a critical form of energy storage in animals, fungi, and bacteria. Its rapid mobilization makes it an essential biochemical reagent and a valuable functional ingredient in research and industrial applications. This product is primarily utilized by the life science research, diagnostic, pharmaceutical, and nutraceutical industries for its role in metabolic studies, as a standard in analytical procedures, and as a potential excipient or energy source.

Application

• Biochemical Research & Standard: Used extensively as a substrate or standard in enzymatic assays for amylase, glycogen phosphorylase, and other carbohydrate-metabolizing enzymes.
• Diagnostic Reagents: Serves as a key component in clinical diagnostic kits for measuring amylase activity in serum and other biological fluids.
• Pharmaceutical Development: Investigated for use as an excipient in drug formulations and as an energy source in cell culture media and stabilization buffers.
• Nutraceutical & Sports Nutrition: Employed in research and product development for rapid energy release and glycogen replenishment studies.
• Microbiology & Fermentation: Acts as a carbon source in microbial culture media for studying bacterial metabolism and in fermentation processes.
• Cell Biology Studies: Utilized in research on cellular energy metabolism, insulin signaling pathways, and glycogen storage diseases.

Quality Control

Our Glycogen is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets stringent specifications for purity, biological source, and performance in enzymatic assays. We provide comprehensive Certificates of Analysis (COA) detailing parameters such as assay, solubility, and absence of contaminating enzymes like amylase. Our production can adhere to cGMP guidelines for applications requiring higher traceability and documentation standards.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the container must be kept in a cool, dry place. For long-term stability, store at 2-8°C. Allow the container to reach room temperature before opening to minimize moisture absorption.
