Overview

CFT for neuroscience research

Cryo-Fluorescence Tomography (CFT) is a powerful imaging tool for neuroscience, where fluorescence reporters can aid in visualization of cell tracking, drug delivery, and pharmacodynamics in the brain. CFT can be used to study the physiology, anatomy, and molecular biology of the brain. In addition, neurodegenerative diseases and other pathologies that affect different regions of the brain and neurological pathways can also be visualized.

EMIT Imaging's visualization tools make CFT data easier to explore and collaborate on, with a full range of options to fit different user types and use cases.

Research examples
Case study · isolated tissue expression at 20 µm

Intracerebral GFP-expressing cell injection

Higher resolution

Findings: Imaging of isolated tissue samples with CFT provides higher resolution than whole-body. In this example, a mouse head was intracerebrally injected with GFP-expressing cells and imaged at 20 µm.

Imaging of mouse head at 20 µm, higher resolution than whole-body CFT
Unlike in vivo fluorescence, CFT works well with GFP
CFT is an ex vivo imaging technique and therefore not hindered by autofluorescence

Case study · enhanced green fluorescent protein (EGFP)

Cell-specific fluorescence reporter imaging

GAD67-GFP

Findings: GAD67-GFP (line G42) mice selectively express enhanced green fluorescent protein (EGFP) in the parvalbumin (Pv)-expressing subclass of basket interneurons (soma, dendrites, and axons) and also in putative presynaptic boutons.
