Combining spectrally resolved detection and fluorescence lifetime multiplexing

Live-Cell Fluorescence Lifetime Multiplexing Using Organic Fluorophores

On-demand video: Imaging more subcellular targets by using fluorescence lifetime multiplexing combined with spectrally resolved detection.

Donor (D) and acceptor (A) molecule which participate in FRET (Förster resonance energy transfer).

What is FRET with FLIM (FLIM-FRET)?

This article explains the FLIM-FRET method which combines resonance energy transfer and fluorescence lifetime imaging to study protein-protein interactions.

Visualizing Protein-Protein Interactions by Non-Fitting and Easy FRET-FLIM Approaches

The Webinar with Dr. Sergi Padilla-Parra is about visualizing protein-protein interaction. He gives insight into non-fitting and easy FRET-FLIM approaches.

Living HeLa cells stained with WGA-488 (yellow), SPY-Actin (cyan), and SiR-Tubulin (magenta). Instant Computational Clearing (ICC) was applied.

How to Perform Dynamic Multicolor Time-Lapse Imaging

Live-cell imaging sheds light on diverse cellular events. As many of these events have fast dynamics, the microscope imaging system must be fast enough to record every detail. One major advantage of…

RNA Quality after Different Tissue Sample Preparation

The influence of sample preparation and ultraviolet (UV) laser microdissection (UV LMD) on the quality of RNA from murine-brain tissue cryo-sections is described in this article. To obtain good…

Projection of a confocal z-stack. Sum159 cells, human breast cancer cells kindly provided by Ievgeniia Zagoriy, Mahamid Group, EMBL Heidelberg, Germany. Blue–Hoechst - indicates nuclei, Green–MitoTracker mitochondria, and red–Bodipy - lipid droplets

New Imaging Tools for Cryo-Light Microscopy

New cryo-light microscopy techniques like LIGHTNING and TauSense fluorescence lifetime-based tools reveal structures for cryo-electron microscopy.

Transverse histological cut of a rabbit tongue. 50 Mpixels images (2326 µm x 1739 µm) in 14 x 18 tiles. Lifetime gives an additional contrast that allows to differentiate different structures in histological stainings.

A Guide to Fluorescence Lifetime Imaging Microscopy (FLIM)

The fluorescence lifetime is a measure of how long a fluorophore remains on average in its excited state before returning to the ground state by emitting a fluorescence photon.
