"Study of protein-probe complexation equilibria and protein-surfactant interaction using charge transfer fluorescence probe Methyl ester of N,N-dimethylamino naphthyl acrylic acid" Subrata Mahanta, Rupashree Balia Singh, Arnab Bagchi, Debnarayan Nath and Nikhil GuchhaitJournal of Luminescence, Volume 130, Issue 6, June 2010, Pages 917-926 Abstract: In this paper, we demonstrate the interaction between intramolecular charge transfer (ICT) probe- Methyl ester of N,N-dimethylamino naphthyl acrylic acid (MDMANA) with Bovine Serum Albumin (BSA) using absorption and fluorescence emission spectroscopy. The nature of probe protein binding interaction, fluorescence resonance energy transfer from protein to probe and time resolved fluorescence decay measurement predict that the probe molecule binds strongly to the hydrophobic cavity of the protein. Furthermore, the interaction of the anionic surfactant Sodium Dodecyl Sulphate (SDS) with water soluble protein BSA has been investigated using MDMANA as fluorescenece probe. The changes in the spectral characteristics of charge transfer fluorescence probe MDMANA in BSA-SDS environment reflects well the nature of the protein-surfactant binding interaction such as specific binding, non-cooperative binding, co-operative binding and saturation binding.
