Pressure injection in continuous sample flow electrophoresis microchips

Pressure pulse injection is proposed as an alternative technique to electrokinetic injection for use in continuous sample flow electrophoresis microchips. During chip operation, sample and buffer solutions are electrokinetically driven near to the entrance ...

Adsorption monitoring device

Hubert Girault, Jean-Pierre Abid

A device for monitoring the adsorption of target molecules on a substrate, the device comprising a substrate (1), at least a portion of which is formed as a thin dielectric layer. A first, modified surface (2) of the layer has ionizable groups of the subst ...

New disposable tubes for rapid and precise biomass assessment for suspension cultures of mammalian cells

Florian Maria Wurm, David Hacker, Martin Jordan, Mathieu Benjamin Stettler, Nicolas Jaccard

We present a new approach for biomass assessment in cell culture using a disposable microcentrifuge tube. The specially designed tube is fitted with an upper chamber for sample loading and a lower 5 microL capillary for cell collection during centrifugatio ...

Metal-bearing and trifluoromethyl-substituted pyrimidines: generation and functionalization

Levente Ondi

5-Pyrimidyllithium species are fairly stable when the metal is flanked by two electron-withdrawing substituents such as trifluoromethyl and chlorine or bromine. Thus, the corresponding 5-carboxylic acids are produced in high yields from 4,5-dibromo-6-(trif ...

Single potential electrophoresis on-chip using Pressure Pulse Injection

Martinus Gijs, Frédéric Lacharme

We propose two new injection techniques for use in electrophoresis microchips, which we call 舖Front Gate Pressure Injection舗 and 舖Back Gate Pressure Injection舗. Both techniques enable a controlled and variable size sample introduction with reduced bias com ...

Multicolor Imaging of Cell Surface Proteins

Kai Johnsson, Nathalie George

The authors report on a method for the multicolor imaging of cell surface proteins which is based on the labeling of carrier protein (CP) fusion proteins with different fluorophores. In one application, different generations of a cell surface protein can b ...

Salt Removal During Off-GelTM Electrophoresis of Protein Samples

Hubert Girault, Niels Erik Lion, Christophe Roussel

The Off-Gel™ technology was recently described for protein fractionation in a solution placed on top of an immobilized pH gradient gel. In addition, this process was found to remove salts from the biological samples to analyze. This desalting effect is stu ...

Observation of B-→J/ψΛp̄ and searches for B-→J/ψΣ0p̄ and B0→J/ψpp̄ decays

Olivier Schneider, Stewart Cole, Mingkui Wang, Chao Wang, Tagir Aushev, Lei Zhang, Sun Hee Kim, Yuan Yuan, Ji Hyun Kim, Jing Li

We report the observation of B-→J/ψΛp̄ and searches for B-→J/ψΣ0p̄ and B0→J/ψpp̄ decays, using a sample of 275×106 BB̄ pairs collected with the Belle detector at the Υ(4S) resonance. We observe a signal of 17.2±4.1 events with a significance of 11.1σ and o ...

DC and transient current distribution analysis from self-field measurements on ITER PFIS conductor

Boris Stepanov

Current reconstruction in cable-in-conduit conductors (CICC) cables is a crucial issue to determine cables performance in working conditions, and must be performed using inverse problem approaches as direct measurement is not feasible. The current distribu ...

Bounds on the k-neighborhood for locally uniformly sampled surfaces

Mark Pauly, Jean Jouve

Given a locally uniform sample set P of a smooth surface S. We derive upper and lower bounds on the number k of nearest neighbors of a sample point p that have to be chosen from P such that this neighborhood contains all restricted Delaunay neighbors of p. ...
