Description

General description

Glycogen is a branched polymer of glucose synthesized by animal cells for energy storage and release. It is constructed of predominantly α1→4 glycosidic bonds with branches created through α1→6 glycosidic bonds.

The Pacific oyster/Crassostrea gigas is a vital marine fishery resource. 20-40% of the dry weight of an oyster accounts for glycogen. High levels of glycogen contribute to the flavor, quality, and hardiness of the oyster.

Application

Glycogen from oyster has been used:

• as a component in acrylamide slab gels to perform branching enzyme activity staining for quantifying ADP-glucose pyrophosphorylase (AGPase) activity
• as a sterile inflammatory agent for inoculating into mice for obtaining peritoneal exudate cells (PEC) and to study its effects on the metabolic functions of macrophages
• as a primer for supplementing maleate buffer for amylosucrase assay to measure the activities of the glutathione S-transferase (GST-AS) amylosucrase fusion protein and the purification fractions
• as a supplement in PreScission buffer to perform polymer synthesis reaction

Oyster glycogen has been used to induce inflammation and to promote extravasation of granulocytes and neutrophils in animal models after intraperitoneal injection. Glycogen also acts as a vascular permeability probe.
