Astbury Centre has outstanding expertise and research infrastructure in all of the major techniques in structural biology
The Astbury Biostructure Laboratory includes the electron microscopy facility within the Faculty of Biological Sciences. We have a range of state-of-the-art equipment for transmission electron microscopy of biological specimens, from small macromolecular complexes to cells, tissues and organisms.
Our facilities are available to researchers from across the University of Leeds, and external users form academia and industry.
Our facility can operate at Biosafety Level II.
The mass spectrometry facility runs routine HDX analyses to determine protein folding states, effects of ligand binding and protein interactions (e.g. epitope mapping). Further advanced instrumentation offers bespoke high-resolution native MS and ion mobility capabilities: Ultra-high mass range Q-Exactive Plus Orbitrap enabling native analysis of heterogeneous systems at high mass-to-charge ratios, e.g. membrane protein lipid complexes, and Tofwerk high-resolution ion mobility TOF (in late 2018) as well as several Waters Synapt HDMS systems.
The NMR facility of the Astbury BioStructure Laboratory in Leeds has several unique capabilities available at 950 MHz. The first is based on direct heteronuclear detection (15N and 13C, 5mm TXO Cryoprobe). The combination of high field and Carbon detection has advantages for complex or large intrinsically disordered proteins. There are also new developments in characterising protein sidechains utilising Carbon detection. Techniques using 15N detection are under development and are of interest in chemically exchanging systems, as an alternative to Ca detection and when deuteration is not feasible. The second is based on using a smaller diameter probe (3mm TCI Cryoprobe) for mass limited samples and high ionic strength samples for optimised sensitivity.
The Astbury Centre brings together researchers from across the University - largely from physics, the biological sciences and chemistry - to allow interdisciplinary approaches to be harnessed to understand the molecular basis of life. The Centre has outstanding expertise and research infrastructure in chemical biology, biophysics and all of the major techniques in structural molecular biology. Together, these approaches are combined with analyses of biological function with the ultimate aim of understanding the molecular basis of biological mechanisms in living cells. Our members address major questions associated with biological mechanisms in areas as diverse as membrane proteins; protein folding and assembly; viruses; and motor proteins.
Electron microscopy, NMR and mass spectrometry services are available through Instruct.
