The FDA Hydrolase Activity Assay Kit is widely used in research and environmental studies to measure hydrolytic enzyme activity in various samples, such as soil, water, and biological tissues. It is particularly valuable in assessing microbial activity and decomposition processes in ecosystems, as it quantifies the breakdown of fluorescein diacetate (FDA) into fluorescein, indicating enzymatic hydrolysis. This kit is also employed in biodegradation studies to evaluate the efficiency of microorganisms in breaking down organic pollutants. Additionally, it serves as a tool in agricultural research to monitor soil health and fertility by measuring enzyme activity linked to nutrient cycling. Its simplicity and sensitivity make it a preferred choice for high-throughput screening in laboratory settings.
