Windows on Neurovascular Pathologies

Discover how innate immunity can sustain deleterious effects following neurovascular pathologies and the technological developments enabling longitudinal studies into these events.

Lifetime-based multiplexing in live cells using TauSeparation. Mammalian cells expressing LifeAct-GFP (ibidi GmbH) and labelled with MitoTracker Green. Acquisition with one detector, intensity information shown in grey. The two markers can be separated using lifetime information: LifeAct-GFP (cyan), MitoTracker Green (magenta). Image acquired with STELLARIS 5.

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.

[Translate to portuquese:] 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.
