Used in environmental and agricultural research to quantify leucine aminopeptidase activity in soil samples, this ELISA kit enables assessment of microbial protein degradation potential. It supports studies on soil health, nutrient cycling, and organic matter decomposition by measuring enzyme levels correlated with nitrogen availability. Researchers apply it in monitoring impacts of land management practices, pollution, or climate change on soil enzymatic activity. The kit is also useful in comparing microbial functional responses across different ecosystems or experimental treatments.
