Used for the detection and quantification of fluorescein diacetate (FDA) hydrolysis activity in soil samples, this ELISA kit helps assess microbial enzymatic activity, which is a key indicator of soil health and biological fertility. The assay measures the rate at which soil microorganisms hydrolyze FDA into fluorescein, reflecting overall microbial metabolic activity. It is widely applied in environmental monitoring, agricultural research, and soil quality assessment to compare microbial activity across different soil treatments, evaluate impacts of pollutants, or study effects of land management practices. The kit offers a rapid, sensitive, and standardized method suitable for laboratory analysis of multiple samples.
