Used in plant biology research to measure the activity of sucrose synthase SS-II, an enzyme involved in sucrose metabolism. This ELISA kit enables scientists to quantify enzyme levels in plant tissues, helping study carbohydrate partitioning, energy metabolism, and plant growth regulation. It is widely applied in studies of crop development, stress responses, and yield improvement, particularly in economically important plants like rice, wheat, and sugarcane. The assay supports high-throughput analysis, making it valuable for screening plant varieties with enhanced sugar utilization or stress tolerance.
