STELLARIS 8 STED with TauSTED from Leica Microsystems allows the study of multiple dynamic events simultaneously and investigation of molecular relationships and mechanisms within the cellular context.
FALCON (FAst Lifetime CONtrast) includes phasors for quantitative FLIM analysis. It is a fully integrated solution for fluorescence lifetime imaging (FLIM) and enables video-rate image acquisition for rapid kinetic studies in live cells.
Features
- Resolving molecular relationships in specimens
- Multiple simultaneous events can be studied at the nanoscale
- 2D and 3D STED imaging
- Significantly reduced light doses due to TauSTED
- Advanced STED-FLIM options with STED and FALCON (full FLIM quantitative tools, phasor FLIM, species separation based on phasor analysis)
- Advanced STED-FCS options
- Fast validation of results on a single platform, from confocal to super-resolution LIGHTNING and STED
- With FALCON it is possible to:
- follow fast molecular interactions via FLIM-FRET (Förster resonance energy transfer).
- use biosensors to detect microenvironmental changes, such as pH or ion concentration.
- apply lifetime contrast to separate multiple fluorophores.
- do analysis using phasor FLIM provides a 2D visualisation of lifetime components. With FLIM phasors you can follow microenvironmental changes, select components to multiplex signal (phasor separation), and determine FRET efficiency.
