Introduction:
Proteomics has matured as a discipline and emerged as a key technology in life science and medical research. It involves the study of protein expression with unprecedented precision and accuracy. Performed at a global level, the discovery, quantitation and analysis of post-translational modifications of thousands of proteins can be performed simultaneously. Alternatively, the use of targeted proteomics techniques can afford extensive coverage of a single pathway or pathways of interest. These technologies can be applied to multiple sample types from whole tissues to sorted cell populations and analysed in conjunction with several separation and quantitative platforms including multiple dimensions of chromatographic separation, 1D/2D gel separations, off gel fractionation, SILAC and iTRAQ stable isotope labelling strategies.
The Department has recently established a strong research proteomics focus with several groups now working with cutting edge instrumentation to address all areas of biochemistry and molecular biology. These include quantitative proteomics, the analysis of a range of post-translational modifications, immunoproteomics, peptide biology, protease biology and structural proteomics.
