Fibrinogen is a large heterogeneous aggregation/degradation-prone protein playing a central role in blood coagulation and associated pathologies, whose structure is not completely resolved. When a high-molecular-weight fraction was analyzed by size-exclusion high-performance liquid chromatography/small-angle X-ray scattering (HPLC-SAXS), several composite(More)
Progress in analytical ultracentrifugation (AUC) has been hindered by obstructions to hardware innovation and by software incompatibility. In this paper, we announce and outline the Open AUC Project. The goals of the Open AUC Project are to stimulate AUC innovation by improving instrumentation, detectors, acquisition and analysis software, and collaborative(More)
Mass spectrometry (MS) is producing high volumes of data supporting oncological sciences, especially for translational research. Most of related elaborations can be carried out by combining existing tools at different levels, but little is currently available for the automation of the fundamental steps. For the analysis of MALDI/TOF spectra, a number of(More)
Hydrodynamic characterisation of (bio)macromolecules is a well-established field. Observables linked to translational friction, such as the translational diffusion (D t 0 (20,w)) and sedimentation ( $$ s_{(20,\text{w})}^{0} $$ s ( 20 , w ) 0 ) coefficients, are the most commonly used parameters. Both can be computed starting from high-resolution structures,(More)
Size-exclusion chromatography coupled with SAXS (small-angle X-ray scattering), often performed using a flow-through capillary, should allow direct collection of monodisperse sample data. However, capillary fouling issues and non-baseline-resolved peaks can hamper its efficacy. The UltraScan solution modeler (US-SOMO) HPLC-SAXS (high-performance liquid(More)
In the original publication of the article, the minus sign is omitted in the last two entries of the last column " BEST Heur " in Table 2. Similar error is also found in Table 3, in the fifth entry under Column 7. The correct version of both Tables 2 and 3 are given for your reading: The online version of the original article can be found under
UltraScan Solution Modeler (US-SOMO) computes hydrodynamic parameters and small-angle scattering data from biological macromolecular structural representations and compares them with experimental data for structural determination and validation. At XSEDE 12, a GUI integrated gateway was introduced to offload large computations to various HPC resources. The(More)
The average pore size ξ0 of filamentous networks assembled from biological macromolecules is one of the most important physical parameters affecting their biological functions. Modern optical methods, such as confocal microscopy, can noninvasively image such networks, but extracting a quantitative estimate of ξ0 is a nontrivial task. We present here a fast(More)
