Used to measure thioredoxin reductase (TrxR) enzyme activity in plant samples, this ELISA kit enables researchers to assess redox status and oxidative stress responses in plants. It is widely applied in plant physiology and stress biology studies, helping to evaluate how plants respond to environmental stresses such as drought, salinity, heavy metals, and pathogens. The kit supports quantitative analysis in research on plant antioxidant systems, contributing to the development of stress-resistant crop varieties and understanding of cellular defense mechanisms.
