Used to measure S-nitrosoglutathione reductase (GSNOR) activity in plant samples, this ELISA kit helps researchers study nitric oxide metabolism and redox regulation in plants. It is widely applied in plant physiology and stress response studies, particularly in understanding how plants respond to environmental stresses such as drought, salinity, and pathogen attack. By quantifying GSNOR activity, scientists can assess the plant's ability to regulate protein S-nitrosylation, a key post-translational modification involved in signaling and defense mechanisms. This kit supports research in crop improvement, plant health monitoring, and development of stress-tolerant plant varieties.
