  • This field is for validation purposes and should be left unchanged.

Measuring of intensity and polarization of a single molecule fluorescence excited by differently polarized excitation gives insights to internal organization of the studied molecule and its orientation in space. Fluorescence resonance energy transfer and fluorescence polarization anisotropy are used to investigate single molecules of the enzyme staphylococcal nuclease. Conoptics manufactures a complete product line used in Forster resonance energy transfer (FRET), Fluorescence-aided molecule sorting (FAMS) and Alternating-laser excitation (ALEX) implementations.
