Glutaminase (GLS) Activity Assay Kit is widely used in research to measure the enzymatic activity of glutaminase, which plays a critical role in cellular metabolism. It is particularly valuable in cancer research, as glutaminase is often upregulated in tumor cells to support their rapid growth and energy demands. By quantifying GLS activity, researchers can study the metabolic reprogramming of cancer cells and evaluate potential therapeutic targets. Additionally, this kit is utilized in neuroscience to explore the role of glutaminase in neurotransmitter synthesis and its implications in neurological disorders. It is also applied in drug discovery to screen and validate inhibitors of glutaminase for therapeutic development. The kit provides a reliable and efficient tool for studying glutamine metabolism in various biological contexts.
