Used for detecting and quantifying S-adenosylmethionine synthetase (SUS) enzyme activity in plant samples. This ELISA kit enables researchers to assess plant metabolic status, particularly in studies related to stress response, growth regulation, and sulfur metabolism. It is widely applied in agricultural research, plant physiology, and biotechnology to monitor enzyme changes under environmental stresses such as drought, salinity, or pathogen attack. The kit provides a reliable and sensitive method for high-throughput analysis in laboratory settings.
