The Kossiakoff Group's research interests are to provide a molecular understanding of how molecular recognition governs virtually all aspects of biological function. To study these issues our group employs a combination of X-ray crystallography and cryo-EM, site-directed mutagenesis, phage display and biophysical analysis. The Kossiakoff group has also pioneered a new technology called “chaperone-assisted” crystallography, which has facilitated the structural analyses of protein systems that had been totally recalcitrant to other approaches. The group has also been at the forefront of developing synthetic antibodies. These synthetic antibodies are much more powerful that traditional monoclonal antibodies and have the potential to completely replace them for uses in live cell imaging and proteomics.
