Phospholipase D (PLD) Activity Assay Kit is widely used in biochemical and pharmaceutical research to measure PLD enzyme activity in various biological samples. It is particularly valuable in studying cell signaling pathways, as PLD plays a critical role in lipid metabolism and membrane dynamics. Researchers utilize this kit to investigate the involvement of PLD in diseases such as cancer, inflammation, and neurodegenerative disorders, helping to identify potential therapeutic targets. Additionally, it is employed in drug discovery to screen and evaluate compounds that modulate PLD activity. The kit is also useful in agricultural research to study plant lipid signaling and stress responses. Its high sensitivity and specificity make it a reliable tool for both basic and applied research in life sciences.
