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.

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.

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.
