Description
ANS (8-Anilino-1-naphthalenesulfonic acid) is a competitive inhibitor targeting thyroxine binding globulin (TBG) (Ki=2.09×106 M-1). ANS is used in radioimmunoassay by displacing bound triiodothyronine (T3) to improve detection sensitivity. ANS can block the protein binding site of T3 and release free T3 for antibody recognition. As a fluorescent probe, ANS can specifically bind to the hydrophobic region of proteins (such as membrane proteins) and monitor the dynamics of protein conformation through changes in fluorescent signals. It is widely used in biochemical research and antibacterial material development[1][2]
