Owing to their close proximity, pericardial fluid (PF)’s proteome may mirror the pathophysiological status of the heart. Despite this diagnosis potential, the knowledge of PF's proteome is scarce. Large amounts of albumin hamper the characterization of the least abundant proteins in PF. Aiming to expand PF's proteome and to validate the technique for future applications, we have fractionated and characterized...
Urine is a highly attractive source of biological information and disease biomarkers, whose proteome characterization is ongoing. To that end, depletion/enrichment strategies for protein analysis can be of great convenience. We have thus developed a method based on the use of EDTA-functionalized magnetic nanoparticles (NPs@EDTA), to fractionate urine samples before liquid chromatography-mass spectrometry...
A new chelating chromatography method was developed based in the use of magnetic iron oxide nanoparticles functionalized with EDTA-TMS ((N-(trimethoxysilylpropyl)ethylenediaminetriacetate trisodium salt). These particles combine a high surface area, biocompatibility and magnetic removal from solution, with the chelating affinity towards metal ions. The particles were used to selectively capture metallo-dependant...
