The Trehalose-6-phosphate synthase (TPS) Activity Assay Kit is primarily used to measure the enzymatic activity of TPS, which plays a critical role in the biosynthesis of trehalose-6-phosphate, a key intermediate in trehalose metabolism. This kit is widely applied in plant biology research to study stress responses, as trehalose-6-phosphate is known to regulate sugar signaling and stress tolerance in plants. It is also utilized in microbiology to investigate the role of trehalose metabolism in microbial survival under extreme conditions, such as desiccation, heat, or osmotic stress. Additionally, the kit is valuable in metabolic studies to understand the biochemical pathways involved in energy homeostasis and carbohydrate metabolism. Its applications extend to agricultural research, where it helps in developing crops with enhanced stress resilience by modulating trehalose pathways.
