Comparison of the simple triexponential deconvolution with the freeform MEM shows that they are qualitatively similar for HSA-Q binding. The MEM is more sensitive to environmental and structural changes in the complex. The HORIBA Jobin Yvon 5000U lifetime spectrofluorometer with TCSPC is an integral part of researching structure-property relations during pro-tein-binding studies for the biochemical and medical fields.

The authors describe the characteristics and application of a 265 nm AlGaN light-emitting diode LED operated at 1 MHz repetition rate, 1.2 ns pulse duration, 1.32 μW average power, 2.3 mW peak power, and ?12 nm bandwidth. The LED enables the ?uorescence decay of weakly emitting phenylalanine to be measured routinely, even in dilute solution. For pH of 6–9.2, the authors ?nd evidence for a biexponential rather than monoexponential decay, providing direct evidence for the presence of phenylalanine rotamers with a photophysics closer to the other two ?uorescent amino acids tryrosine and tryptophan than has previously been reported. © 2006 American Institute of Physics. ?DOI: 10.1063/1.2245441?

We demonstrate an AlGaN light-emitting diode LED giving pulses of ?600 ps full width half maximum, 0.35 ?W average power, 0.6 mW peak power, and ?12 nm bandwidth at 295 nm. This source is ideal for protein intrinsic tryptophan ?uorescence decay research without the unwanted excitation of tyrosine and paves the way to lab-on-a-chip protein assays using ?uorescence decay times. Fluorescence decay and anisotropy decay measurements of human serum albumin are reported and the usefulness of the 295 nm LED demonstrated in comparisons with a nanosecond ?ashlamp and LEDs with nominal wavelength emission of 280 nm. © 2005 American Institute of Physics.[ DOI: 10.1063/1.1984088?]
