Used for detecting and quantifying soil nitrous oxide (N₂O) reductase enzyme activity, this ELISA kit enables researchers to assess microbial function in environmental samples. It is widely applied in agricultural and environmental studies to monitor nitrogen cycling, evaluate greenhouse gas emissions, and study the impact of fertilizers or soil management practices on microbial communities. The kit provides a sensitive and specific method to measure enzyme activity linked to N₂O reduction, helping in the development of strategies to mitigate climate-active gas emissions from soils.
