Used in plant biology research to measure UTP-glucose-1-phosphate uridylyltransferase (GPT) enzyme activity in plant tissues. This ELISA kit enables researchers to quantify GPT levels, which play a key role in sucrose and starch metabolism. It helps in studying carbohydrate regulation, energy metabolism, and plant response to environmental stresses such as drought, cold, or nutrient deficiency. The assay is useful for screening genetically modified plants, evaluating metabolic engineering outcomes, and understanding photosynthetic efficiency in crops. Suitable for use with leaf extracts and other plant samples where metabolic enzyme activity needs precise measurement.
