Used for the quantitative detection of nitrite reductase (NirS) enzyme activity in soil samples, this ELISA kit enables researchers to assess microbial denitrification potential in environmental studies. It is particularly valuable in agriculture and ecology for monitoring nitrogen cycling, evaluating soil health, and understanding greenhouse gas emissions like nitrous oxide. The kit supports high-throughput analysis, making it suitable for field studies and long-term soil monitoring programs. By measuring NirS activity, it helps in comparing microbial communities across different soil types, management practices, or environmental conditions.
