Description

Application

8-Anilino-1-naphthalenesulfonic acid (ANS) has been used to study the thermal aggregation of BSA (bovine serum albumin).

Biochem/physiol Actions

8-Anilino-1-naphthalenesulfonic acid (ANS) is an important dye which is used to study the intermediate states in the folding/unfolding pathways of proteins. It is also useful to check the conformational changes involved with the aggregation of proteins. ANS is nonfluorescent in the aqueous solution, however, it fluoresces strongly upon binding to BSA (bovine serum albumin) and denatured proteins. It is used for the detection of albumin in the serum. ANS mainly interacts with the solvent exposed nonpolar (hydrophobic) sites.
