Used in plant biology research to quantify sucrose phosphate phosphatase (SPP) enzyme levels in plant tissues. This ELISA kit enables researchers to study sucrose metabolism, particularly in pathways related to photosynthesis, carbohydrate allocation, and sugar regulation under various environmental or developmental conditions. It is commonly applied in studies of plant stress responses, growth regulation, and metabolic engineering of crops. The assay provides a sensitive and specific method to measure SPP protein concentration in leaf extracts, seedlings, or other plant samples, supporting advances in agricultural science and plant biotechnology.
