Used in plant physiology and agricultural research to detect and quantify vacuolar invertase (VIN) enzyme levels in plant tissues. This kit enables researchers to study sugar metabolism, particularly in crops like tomatoes, potatoes, and sugarcane, where VIN activity influences sweetness, yield, and stress responses. By measuring VIN concentration via ELISA, scientists can assess how environmental stresses such as drought or cold affect carbohydrate partitioning and plant development. It is also applied in breeding programs to screen varieties with improved sugar content or stress tolerance. The kit supports high-throughput analysis, making it valuable for both laboratory research and agricultural biotechnology development.
