Cambridge Institute for Medical Research



Our facility supports a range of structural and computational research laboratories using X-ray crystallography, cryo electron microscopy, molecular modelling and new method development. Our structural biology research is providing new insights into the molecular mechanisms underlying a range of human diseases. Our users combine structural work with complementary methods in cell biology, biochemistry and biophysics to develop a comprehensive understanding of fundamental biological processes.

Protein Crystallography

The facility has high-throughput robotics for protein crystallisation including:

Mosquito LCP Crystallisation Robotics for nanoscale drop setting

Formulatrix Rock Imager for dynamic monitoring of protein crystallisation:

We have regular access to synchrotron light sources including Diamond Light Source for remote access data collection and data processing.

Cryo-electron microscopy

Within the CIMR we have access to infrastructure for the preparation of cryo-EM samples including:

Vitrobot for plunge freezing cryo-EM samples

For data collection we have access to the electron microscope facility in the Department of Biochemistry.

Software Development

Within CIMR we have a research team dedicated to the development of new computational methods for the improvement of structure determinaton and refinement.

Phaser is a program for phasing macromolecular crystal structures using maximum likelihood methods and is part of the Phenix  and CCP4 software suites for structural biology.


ISOLDE  is an interactive environment designed to ease the task of building high-fidelity atomic models in challenging low-resolution crystallographic and cryo-EM datasets by making use of GPU-accelerated interactive molecular dynamics combined with real-time geometric validation.
