The Division of Structural Biology has a world leading reputation for structural biology research within the University of Oxford, UK
Producing a functional mammalian protein or protein complex often necessitates using a mammalian host to ensure appropriate post-translational modifications (e.g.,disulfide bonds, glycosylation, phosphorylation) are added to the protein. Expression in a variety of mammalian cells in Strubi utilizes constitutive and inducible expression. Transient expression is the most usual method, but targeted integration vectors for stable cell generation as well as lentiviral delivery vectors for difficult to transfect cells are also in use and available to the access visitor. Adherent and suspension cell lines are available for large-scale protein production. Expression in the mammalian cell system offered through Instruct includes protein purification and can also manage post-translational modification (please enquire).
Nanolitre crystallisation, using standard plate technology is the norm to produce diffraction quality crystals sufficient for structure determination. Miniaturisation and automation has resulted in the growth of a wider variety of proteins, under a broad range of standardised conditions, that can be crystallised. In Strubi, crystallisation can be set up using plate technologies or increasingly, microfluidic and capillary technologies, which allow in situ diffraction both in house and at the beamline, thereby accelerating data collection. Strubi has invested in a high degree of automation, for crystallisation set-up, crystal storage and imaging. A range of crystallisation screens are available for soluble and membrane proteins as well as crystallisation at 5oC.
The Division of Structural Biology (STRUBI) at the University of Oxford is located about 1.5miles (2Km) from Oxford city centre, next to the Churchill Hospital site. Housed in the Wellcome Centre Human Genetics on the Old Road Campus, it has easy connections with bus and train transport from airports, London and Oxford Centre.
The Wellcome Trust Centre for Human Genetics has its own busy cafeteria as well as seminar and meeting rooms. Other academic buildings nearby have other catering facilities that may be available to you. There are shops in Headington (the nearest retail area) within walking distance (10-15 minutes from Strubi), and the centre of Oxford is a short bus or cycle ride away.
Oxford is a busy University town and many of the University colleges, museums and exhibitions are free and open to the public. More information about Oxford can be found here.
OPIC houses state-of-the-art biosafety containment laboratories at ACDP category 3 and DEFRA 4 levels of containment. This facilitates the study of a number of viruses that are important to human and animal health. We have a range of state-of-the-art equipment for transmission electron microscopy of biological specimens, from small macromolecular complexes to cells. Our facilities are available to researchers from across the University of Oxford, and external users form academia and industry.
OPIC houses state-of-the-art equipment for cryo-EM. This includes a Titan Krios (Thermo Fisher Scientific) 300-kV transmission electron microscope equipped with Falcon III and K2 Summit/GIF (Gatan) direction electron detectors, in addition to a Glacios (Thermo Fisher Scientific) 200-kV, also equipped with a Falcon III, as well the facilities for the preperation of cryo-EM sample grids.
