Glycogen Assay Kit

Description

Glycogen is a polysaccharide that is the principal storage form of glucose in animal and human cells. Glycogen is made primarily by the liver and muscles, but it can also be made by glycogenesis within the brain and stomach. Cayman’s Glycogen Assay provides a simple, reproducible, and sensitive tool for assaying glycogen from tissue. In this assay, glycogen is hydrolyzed by amyloglucosidase to form β-D-glucose, which is then specifically oxidized to D-glucono-δ-lactone by glucose oxidase forming hydrogen peroxide in the process. Hydrogen peroxide, in the presence of horseradish peroxidase, reacts with 10-acetyl-3,7-dihydroxyphenoxazine (ADHP) in a 1:1 stoichiometry to generate the highly fluorescent product resorufin which is measure at an excitation wavelength of 530-540 nm and an emission wavelength of 585-595 nm.

Uses

Glycogen Assay Kit has been used in glycogen quantification. It has also been used to determine the glycogen content in liver, vastus lateralis and muscle homogenates.

General Description

Glycogen is a branched polymer of glucose that serves as the primary short-term energy storage molecule in animals. Glycogen is primarily synthesized in liver and muscle tissue where it can constitute up to 10% of the weight of liver and 1-2% of the weight of muscle tissue. While muscle glycogen is generally utilized locally, liver glycogen serves as an important buffer to regulate blood glucose levels. Glycogen metabolism is dysregulated in diabetes and the glycogen storage diseases due to inborn errors of metabolism.
