GTP Tris solution is widely used in biochemical and molecular biology research as a critical component in various enzymatic reactions. It serves as a substrate or energy source in processes like protein synthesis, signal transduction, and nucleic acid metabolism. This solution is particularly essential in studies involving GTP-binding proteins (G-proteins), where it helps in understanding cellular signaling pathways. Additionally, it is utilized in assays to measure enzyme activity, such as kinases and GTPases, providing insights into their mechanisms and regulation. Its stability and compatibility with biological systems make it a valuable tool in experimental protocols requiring precise GTP concentrations.
