If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

일반 설명
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.
Glycogen, a polysaccharide of glucose, serves as the primary storage of glucose in the body and functions as a vital energy reserve in both fungi and animals. With its multibranched structure, glycogen is a secondary long-term energy storage molecule, similar to starch, and closely related to amylopectin, playing a pivotal role in energy storage and release and existing as granules in the cytoplasm.
In research, glycogen is commonly employed to investigate carbohydrate storage, metabolism, and enzyme characterization. Serving as an inert carrier, it significantly enhances the efficiency of DNA and RNA extraction through ethanol precipitation. Its versatility proves valuable in unraveling the intricate details of the glucose cycle, contributing to advancements in diverse areas of physiological, nutritional, biochemical, and cell biology research.

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.
애플리케이션
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.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 답변-
Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

We intend to use G8751 for a phantom in MRI C13 spectroscopy and need to know the concentration more precisely than just >75%, so we can adjust to 100% in the phantom and avoid a large margin of error in glycogen spectroscopy measurements of patients.
