Glycogen Assay Kit II (Colorimetric) (CAT#: CB-P146-K) Datasheet

Product Type
The Glycogen Assay Kit II (colorimetric) provides a simple, fast and reliable to measure the glycogen content in biological samples.
This glycogen assay is suitable for measuring the glycogen content in samples containing reducing substances, which may interfere with oxidase-based assays (such as our most popular glycogen assay kit.
In this glycogen assay protocol, glycogen is hydrolyzed to glucose, and then oxidized to form an intermediate, which reduces the colorless probe to a colored product with strong absorption at 450 nm. This high-throughput suitable assay kit can detect 4-40 µg/ml glycogen in samples.

Figure 1 Glycogen measured in cell lysates showing quantity (µg) per 1 mln cells.
Samples with the concentration of 1e7 cells/mL (HeLa) and 6.6e6 cells/mL (HCT116) were used. Samples were diluted 2-6 fold.

Figure 2 Glycogen measured in tissue lysates showing quantity (µg) per mg of extracted protein.
Protein concentration for samples varied from 25 mg/mL to 50 mg/mL. Samples were diluted 2-54 fold.

Figure 3 Standard curve: mean of duplicates (+/- SD) with background reads subtracted

Figure 4 Glycogen level was highest in Alstonville larvae (n = 10 biological rep/mitotype).
