Used in agricultural and plant biology research to quantify nitrite reductase enzyme levels in plant tissues. Helps assess nitrogen assimilation efficiency, monitor plant response to nitrogen availability, and evaluate stress conditions such as nitrate deficiency or toxicity. Widely applied in studies focused on improving crop nutrient use efficiency and sustainable farming practices. Enables researchers to measure enzyme activity in leaves, roots, and other plant parts with high sensitivity and specificity. Suitable for experiments involving genetically modified plants, fertilizer optimization, and environmental impact studies.
