Luciferin potassium salt is a luminescent substrate used in bioluminescence assays. The substrate is oxidized by luciferase enzymes to produce light, making it ideal for cell assays, enzyme activity detection, and ATP measurements. This 3g quantity is highly concentrated and suitable for a variety of applications, including gene expression studies, cellular viability assays, and metabolic activity analysis. The bioluminescent reaction is highly sensitive and provides rapid results, allowing researchers to quantify enzyme activity and monitor cellular processes in real time. Luciferin is commonly used in biological research and diagnostic assays, offering a powerful tool for detecting low levels of biological activity.
