D-Luciferin Sodium Salt (50mg) is a bioluminescence substrate commonly used in high-sensitivity detection assays. When oxidized by luciferase, it generates light, enabling the detection of ATP and the measurement of cellular activity. The sodium salt form of D-Luciferin is favored for applications that require stable light emission, making it essential in biological assays, including ATP monitoring, enzyme activity studies, and cell viability tests. This product is particularly useful in molecular biology, environmental testing, and pharmaceutical research, providing excellent luminescent signals for quantification in high-throughput screening systems.
