Presentation Fluorimeter


Fluorescence spectroscopy is a powerful technique that allows analysis at equilibrium or in real time, changes in the environment of intrinsic or extrinsic fluorescent probes (including tryptophan for protein, synthetic fluorophores).
The Biophysical Platform has a high sensitivity fluorometer multimodular (Quantamaster QM4CW ; Manufacturer : Photon Technology International) equipped with several modules to measure the fluorescence steady state in normal or polarized light (fluorescence anisotropy measurements) or the lifetime of fluorescence.
Two types of quantities can be quantified with the instrument: the intensity and polarization (or anisotropy) of fluorescence, static measurements (equilibrium) or dynamic ("stopped-flow).


The technology can be applied both to the study of:

  • conformational stability of macromolecules
  • characterization of molecular interactions
