2-O-alpha-Mannosylglycerate, a negatively charged osmolyte widely distributed among (hyper)thermophilic microorganisms, is known to provide notable protection to proteins against thermal denaturation. To study the mechanism responsible for protein stabilization, pico-second time-resolved fluorescence spectroscopy was used to characterize the thermal unfolding

We present a label-free detection of protein interaction between beta-galactosidase from Escherichia coli (Ecbeta-Gal) and monoclonal anti-Ecbeta-Gal using deep UV laser-based fluorescence lifetime microscopy. The native fluorescence from intrinsic tryptophan emission was observed after one-photon excitation at 266 nm. Applying

The effects of heavy water (D(2)O) on internal dynamics of proteins were assessed by both the intrinsic phosphorescence lifetime of deeply buried Trp residues, which reports on the local structure about the triplet probe, and the bimolecular acrylamide phosphorescence quenching

Fluorescence is a proven tool in all fields of knowledge, including biology and medicine. A significant obstacle in its use is the nonlinearity of the dependence of the fluorescence intensity on fluorophore concentration that is caused by the so-called primary

Bovine beta-lactoglobulin A (BLGA) is a well characterized globular protein whose tertiary structure has been investigated in detail. BLGA undergoes a pH-dependent conformational change which X-ray data described as involving mostly the loop connecting strands E and F and the
