What is glycogen synthase?
Glycogen synthase is an enzyme responsible for the synthesis of glycogen from glucose.
Why avoid radioactive isotopes?
Radioactive isotopes pose health risks and regulatory challenges, making non-radioactive methods preferable.
What equipment is needed for the assays?
A simple spectrophotometer and basic laboratory supplies are sufficient for the assays.
How does the assay work?
The assay measures the activity of glycogen synthase by monitoring changes in absorbance related to substrate conversion.
Can these methods be applied to other enzymes?
Yes, the techniques can potentially be adapted for studying other metabolic enzymes.
