The Sorbitol Dehydrogenase (SDH) Activity Assay Kit is primarily used to measure SDH enzyme activity in biological samples, which is crucial for understanding metabolic processes related to glucose and sorbitol pathways. It is widely applied in research focused on diabetes, as SDH plays a role in the polyol pathway, which is implicated in diabetic complications like neuropathy and retinopathy. The kit is also utilized in studies of liver function, as SDH is a biomarker for liver injury or disease. Additionally, it aids in evaluating the efficacy of therapeutic agents targeting metabolic disorders. Its applications extend to plant biology, where it helps analyze sugar metabolism in plants under stress conditions. The kit provides a reliable and sensitive method for assessing SDH activity, making it valuable in both clinical and research settings.
