Measuring Unfolding of Proteins in the Presence of Denaturant Using Fluorescence Correlation Spectroscopy

IFABP is a small (15 kDa) protein consisting mostly of antiparallel β-strands that surround a large cavity into which ligands bind. We have previously used FCS to show that the native protein, labeled with fluorescein, exhibits dynamic fluctuation with a relaxation time of 35 μs. Here we report the...
