Used in plant physiology research to quantify levels of 6-sorbitol phosphate dehydrogenase (S6PDH), this ELISA kit enables scientists to study enzyme activity involved in sorbitol metabolism. It is particularly useful in analyzing carbohydrate transport and storage in plants such as apple, pear, and other rosaceae species where sorbitol is a major photosynthetic product. Researchers use the kit to investigate stress responses, fruit development, and source-sink relationships in plant tissues. The assay supports high-throughput analysis, making it valuable for agricultural studies aiming to improve crop yield, fruit quality, and abiotic stress tolerance.
