Sensor Technologies' (ST) Quantumxpert FCS spectrometer offers wash-free measurement of interactions between proteins, nucleic acids and other macromolecules at the single-molecule level.
The Quantumxpert fluorescence correlation spectrometer (FCS) detects macromolecular binding in-vitro of 10-300ul samples at nanomolar concentrations.
FCS is a single-module technique that monitors changes in molecule/complex size and stoichiometry, providing valuable information about macromolecular binding.
Additionally, FCS provides a direct measure of concentration based on detection of fluorescent particles in a defined illumination volume, allowing one-step measurement of sample concentration without the need for standard curves.
