Life Science applications of synchrotron light

Pharmaceutical companies and academic researchers are making increasing use of macromolecular crystallography. Improvements in the speed of data collection and solving structures mean that it is now possible to obtain structural information on a timescale that allows chemists and structural biologists to work together in the development of promising compounds into drug candidates.

Membrane proteins are estimated to represent up to 30% of the gene products of a typical genome, and are of considerable interest to the pharmaceutical industry (almost 50% of drug compounds in clinical use are targeted at membrane proteins). The microfocus MX beamline I24 and the onsite Membrane Protein Laboratory enable structural studies of this challenging group of proteins.

Non-crystalline diffraction studies are vital to gaining a better understanding of activities such as protein denaturation, emulsification and phase separation, binding and unbinding, and the control of interfaces. Some diseases involve a change in the fold of a protein, so that the protein becomes pathogenic (for example Creutzfeld-Jacob-Desease (CJD), Alzheimer's Disease, BSE).

Circular dichroism is a spectroscopic technique which enables the study of molecular interactions - an exponentially growing area in the field of structure-function relationships of biologically important molecules. Infrared microspectroscopy allows not only molecular identification but also spatial resolution, which is necessary to the understanding of the physical-chemical properties of the vast range of materials and surfaces that are organised on a microstructural level. These include biomedical samples like tissue and or single cells that can be mapped in plots showing molecular composition versus position by IR imaging technique.
