Figure 1

(a) Fluorescence spectra and (b) urea-induced unfolding of PIMT and PIMT in presence of AuNSs of different sizes in 1:1 molar ratio. Samples were excited as 295 nm in 0.1 M sodium phosphate buffer pH 7.2. (c) Fluorescence spectra of bis-ANS alone, and in presence of PIMT and PIMT-AuNS conjugates (in 1:1 molar ratio) in presence of bis-ANS. Protein concentration of 5 μM was used and the samples were excited at 395 nm. (d) Titration using fluorescence intensity against bis-ANS concentration, in presence of PIMT and PIMT-AuNS conjugates.
