ANSA (8-Anilino-1-naphthalenesulfonic acid) is a hydrophobic polarity sensitive fluorescent dye useful as a site probe to detect conformational changes in cell and micelle membranes and molecules such as proteins. ANSA is also used as a fluorescent probe for the estimation of the critical micelle concentration (CMC) of surfactants.

We have studied the metal-catalyzed oxidation (MCO) of brain-derived neurotrophic factor (BDNF) with regard to target sites and potential conformational changes of the protein. The exposure of BDNF to three different levels of ascorbate/Cu(II)/O2 [20 microM Cu(II), 2 mM ascorbate

Protein aggregation is believed to be due to conformers that expose hydrophobic clusters that promote protein association. Such conformers can be detected using a fluorescent probe like 8-anilino 1-naphthalenesulfonic acid (ANSA). Here we show that urease exposed to 1.0 M

Canavalia ensiformis (jack bean) alpha-urease is a hexameric protein characterized by a complex denaturation mechanism. In previous papers, we have shown that a hydrophobic 8-anilino-1-naphthalenesulfonic acid (ANSA) binding conformer could be populated in a moderate concentration of denaturant. This state
