Quantifoil and the revolution of cryo-electron microscopy: a precision support for structural research
In the field of structural biology and nanoscience, cryo-electron microscopy (cryo-EM) has revolutionised the analysis of macromolecular structures. One of the key elements in this cutting-edge technique is the support used to immobilise the samples: the microscopy grid. Among all the options available on the market, Quantifoil® grids have established themselves as the global standard.
Why are Quantifoil grids so important?
Compatibility with the latest generation of microscopes
The Quantifoil grids are designed to be perfectly compatible with the most advanced electron microscopes.
Background noise reduction
The ultrathin amorphous carbon film used in Quantifoil grids reduces background noise and interference, which improves the signal-to-noise ratio, a crucial element for achieving atomic resolution.
Uniform vitrification
Thanks to the well-calibrated holes, the ice layer containing the sample is vitrified uniformly, without crystallisation, a crucial criterion for successful cryo-EM..
Applications of Quantifoil grids
The Quantifoil grids are used in many disciplines:
- Study of membrane proteins, ribosomal complexes or viruses
- Analysis of nanoparticles, polymers or exosomes
- Electron tomography and 3D reconstructions of biological complexes
- Correlative microscopy (CLEM) combining fluorescence and EM

Typical Cryo-EM Workflow
- Purified protein shipped to the Cryo-Electron Microscopy Center (CEMC)
- Plunge freezing of the protein sample on a TEM grid
- Cryo grid screening and validation
- Data collection
- Remote data delivery
- Data analysis and 3D structure determination
