Used to detect and quantify Spermidine Synthase (SPMS) enzyme activity in plant samples, this ELISA kit supports research in plant physiology and stress response. It helps scientists study polyamine biosynthesis, which plays a key role in plant growth, development, and resistance to environmental stresses such as drought, salinity, and pathogen attack. The kit is widely used in agricultural research and genetic engineering to evaluate transgenic plants or treatments that modulate polyamine levels for improved crop performance.
