| Affinity analysis of point mutated proteins is used to complement crystallographic data on interactions between (1) the zinc finger domain and an adjacent helix on an exchange factor, Rabex-5, and (2) ubiquitin. Biacore T100 data are crucial in defining how both domains on Rabex-5 are necessary for recognition of ubiquitin and subsequent ligase activity. |

| Anal Biochem 334: 367-75 (2004) |
On the direct capture of synaptic vesicles from neurons as a means to study synapse-specific membrane proteins on a sensor surface. The paper is rich in experimental detail and the method is proposed as a general approach to differential proteomics, or the use of organelles as markers or pharmacological targets. |

| Nucleic Acids Res 32: e44 (2004) |
A high-throughput approach to quantify DNA-protein interactions, which can aid the identification of functional genetic polymorphisms. Biacore experiments support microarray data based on fluorescent reading. The method was tested on two distinct transcription factors. Biacore’s experimental conditions and data analysis are well described. |

| J Biol Chem 279: 31788-95 (2004) |
| On the interaction between prefoldins and group II chaperonins. This is shown to be important in protein folding, assembly, transport, and degradation. Contains an excellent explanation of the assay and analysis. |

| Membrane association, electrostatic sequestration, and cytotoxicity of Gly-Leu-rich peptide orthologs with differing functions |
| D. Vanhoye, F. Bruston, S. El Amri, A. Ladram, M. Amiche and P. Nicolas |
| Biochemistry 43: 8391-409 (2004) |
Detailed study on the power of Biacore kinetic analysis to rationally deduce the mechanisms by which cationic peptides bind and disrupt bacterial membranes, leading to cell death. The peptides are potentially therapeutic in humans: the task is to find those that are bactericidal but non-toxic to eukaryotic cells. The authors achieve this by constructing and immobilizing prokaryotic-like and eukaryotic-like membranes on a sensor surface and observing peptide binding patterns. |
