Sodium taurodeoxycholate hydrate is widely used in biochemical research as a bile salt surfactant. It plays a crucial role in solubilizing membrane proteins and lipids, making it essential for studying cell membrane structures and functions. It is also utilized in the extraction of DNA and RNA from cells, facilitating efficient isolation. In drug delivery systems, it enhances the absorption of poorly soluble drugs by improving their solubility and permeability. It is employed in the formulation of cell culture media to mimic physiological conditions, aiding in the growth and maintenance of cells. Additionally, it is utilized in diagnostic assays to stabilize enzymes and proteins, ensuring accurate and reliable results.
