Product Data Sheet
ANS
Catalog No. A24903
ANS (8-Anilino-1-naphthalenesulfonic acid) is a competitive inhibitor of thyroxine binding globulin (TBG), exhibiting a Ki value of 2.09×10^6 M^-1. This compound is utilized in radioimmunoassays to enhance detection sensitivity by displacing bound triiodothyronine (T3) and facilitating its recognition by antibodies. Additionally, ANS serves as a fluorescent probe, selectively binding to hydrophobic regions of proteins, particularly membrane proteins, allowing for real-time monitoring of protein conformational dynamics through fluorescence changes. Its applications extend to biochemical research and the development of antibacterial materials.
