RATIONALE Rapidly performing global proteomic screens is an important goal in the post-genomic era. Correlated matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) and fluorescent imaging of photocleavable peptide-coded random bead-arrays was evaluated as a critical step in a new method for proteomic screening that combines many of the advantages of MS with fluorescence-base...

BACKGROUND New technologies for the detection of early-stage ovarian cancer are urgently needed. Pathological changes within an organ might be reflected in proteomic patterns in serum. We developed a bioinformatics tool and used it to identify proteomic patterns in serum that distinguish neoplastic from non-neoplastic disease within the ovary. METHODS Proteomic spectra were generated by mass ...

Many transmembrane receptors are regulated by associations with scaffold proteins containing PDZ domains, which interact with receptor carboxyl-termini to control receptor signaling, trafficking, and localization. We describe here approaches for detecting and characterizing interactions between receptors and PDZ scaffolds. These approaches include the construction and screening of proteomic arr...

Automated acquisition of high resolution, light microscope images of cells is becoming a common requirement in modern proteomic and cellomic research. A prerequisite for such microscopy is fine focus tuning, commonly optimized by multiple exposures, followed by image sharpness analysis. We describe here an extremely fast and accurate laser autofocusing system with distinct advantages for large-...

BACKGROUND 5% of first time pregnancies are complicated by pre-eclampsia, the leading cause of maternal death in Europe. No clinically useful screening test exists; consequentially clinicians are unable to offer targeted surveillance or preventative strategies. IMPROvED Consortium members have pioneered a personalised medicine approach to identifying blood-borne biomarkers through recent techno...
