Used to measure sucrose phosphate synthase (SPS) enzyme activity in plant tissues, this ELISA kit helps researchers study carbohydrate metabolism and sugar regulation in plants. It is widely applied in plant physiology and agricultural research to evaluate how environmental stresses like drought, temperature, or salinity affect sugar production and plant growth. The kit supports high-throughput analysis, making it useful in breeding programs and genetic studies aimed at improving crop yield and stress tolerance. It is also employed in studies of photosynthesis efficiency and source-sink relationships in crops such as rice, wheat, and sugarcane.
