Live-cell imaging
Track how the lifetimes in your sample change over time with the built-in time-lapse feature. Just set the duration and time between measurements and our software does the rest.
This video shows a time-lapse of HeLa cells. After 150 seconds isoproterenol is added, which results in a rapid increase of cAMP and a corresponding increase in fluorescence lifetime. This is followed by cAMP decomposition and a steady decrease in fluorescence lifetime.

Single-image FLIM
Demonstration of the Lambert Instruments Toggel camera for single-image FLIM (siFLIM) detection of histamine-induced alterations in Ca2+ concentration. Tiny oscillations in Ca2+ levels (~2.5 s periods) are observed after addition of histamine. Such small and rapid transients would go completely unnoticed when recorded by conventional FLIM.

Bacteria research
B. subtilis cells where GFP-tagRFP fluorophores are linked are mixed in a 1:1 ratio with B. subtilis cells where the GFP-tagRFP fluorophores are cleaved apart; resulting in a mix of cells with either short GFP fluorescence lifetime due to quenching by tagRFP or long GFP fluorescence lifetime.

High-throughput screening
Researchers at the University of Amsterdam developed a multi-position fluorescence lifetime imaging (FLIM) screening method to screen for bright FPs. However, this method can be applied to any experiment in which the fluorescence lifetime is an important parameter.
