Fluorescence anisotropy measurements in solution: Methods and reference materials (IUPAC Technical Report)

摘要

After recalling the basic relations relevant to both steady-state and time-resolved fluorescence polarization, it is shown how the values of steady-state polarized intensities recorded experimentally usually need to be corrected for systematic effects and errors, caused by instrumentation and sample properties. A list of selected reference values of steady-state fluorescence anisotropy and polarization is given. Attention is also paid to analysis of time-resolved fluorescence anisotropy data obtained by pulse fluorometry or phase and modulation fluorometry techniques. Recommendations for checking the accuracy of measure ments are provided together with a list of selected time-resolved fluorescence anisotropy data as reported in the literature.
