The Glycogen-Glo™ Assay is a fast and sensitive method for detecting glycogen from various biological samples, such as cultured cells and tissue homogenates. Based on bioluminescent technology, the Glycogen-Glo™ Assay can detect subtle changes in glycogen synthesis, storage and breakdown. Its streamlined sample preparation protocol involves acid treatment and neutralization directly in the assay wells, eliminating the need for cell collection, centrifugation and spin columns. The assay is adaptable to a 384-well format, facilitating quick analysis of many samples.
