Glycogen Assay Kit ab65620 is an easy and accurate assay to measure glycogen levels in biological samples. In the glycogen assay protocol, glucoamylase hydrolyzes the glycogen to glucose which is then specifically oxidized to produce a product that reacts with OxiRed probe to generate color (570 nm) and fluorescence (Ex 535/Em 587). The assay can detect glycogen 0.0004 to 2 mg/ml.
Glycogen assay protocol summary:
- add samples and standards to wells
- add hydrolysis enzyme mix and incubate for 30 min
- add reaction mix and incubate for 30 min
- analyze with microplate reader
If your sample is likely to contain reducing substances, we recommend using Glycogen Assay Kit II (ab169558), as reducing substances may interfere with the assay detection method.
This product is manufactured by BioVision, an Abcam company and was previously called K646 Glycogen Colorimetric/Fluorometric Assay Kit. K646-100 is the same size as the 100 test size of ab65620.

RelevanceGlycogen is the primary short term energy storage molecule in animals. It is synthesized primarily in the liver and muscle. Glycogen is a highly branched polymer of glucose molecules, connected with an alpha-1,4 linkage, branching via an alpha-1,6 linkage. Abnormal ability to utilize glycogen is found in diabetes and in several genetic glycogen storage diseases.
Total glycogen levels in C576bL6 mice astrocytes were determined by using Glycogen assay kit (ab65620). At 24 hours following OGD-reoxygenation, astrocytes had less glycogen levels compared to normoxia control. Astrocytes treated with Methylene blue (MB) showed a higher glycogen content compared to non-MB treated, OGD-reoxygenation astrocytes. * p < 0.05; ## p < 0.001 Vs. OGD-reoxygenation control / 0 μM MB.
