High-temp. polymn. has recently become of interest for industry because it yields higher reaction rates, and thus less reaction time, lower viscosity, and higher conversions. However, it also leads to new challenges for process engineering in regards to ma ...
A nanoreactor based on mesoporous silicates is described for efficient tryptic digestion of proteins within the mesochannels. Cyano-functionalized mesoporous silicate (CNS), with an average pore diameter of 18 nm, is a good support for trypsin, with rapid ...
Recently, a new method for the specific covalent labeling of fusion proteins in vitro and in living cells has been developed. This method is based on the unusual mechanism of a DNA repair protein: the O6-alkylguanine DNA alkyltransferase (AGT). In addition ...
A new protein fractionation technique based on off-gel isoelectric focusing (IEF) is presented, where the proteins are separated according to their isoelectric point (pI) in a multiwell device with the advantage to be directly recovered in solution for fur ...
The electrochemically induced mass spectrometric tagging of cysteines by substituted hydroquinones was studied for peptides in a classical electrospray solvent (i.e., MeOH/H2O/AcOH 50/49/1). The tagging efficiency was tested with different hydroquinone com ...
Organic–inorganic hybrid materials were prepared using the sol–gel process in order to improve the scratch resistance of poly(methyl methacrylate) (PMMA) substrates. Sol–gel solutions based on tetraethoxysilane and α,ω-triethoxysilane terminated polycaprol ...
Membrane-associated proteins of Mycobacterium tuberculosis offer a challenge, as well as an opportunity, in the quest for better therapeutic and prophylactic interventions against tuberculosis. The authors have previously reported that extraction with the ...
A microchip reactor has been developed on the basis of a layer-by-layer approach for fast and sensitive digestion of proteins. The resulting peptide analysis has been carried out by matrix-assisted laser desorption ionization timeof- flight mass spectromet ...
Recent advances in peptide fragmentation techniques and mass spectrometry have opened up the possibility of combining peptide sepn. techniques, such as capillary electrophoresis (CE) and capillary liq. chromatog., with Fourier transform ion cyclotron reson ...
Scanning electrochemical microscopy (SECM) was used to image silver-stained proteins on a poly(vinylidene difluoride) membrane. The method is based on measuring the current at a scanning microelectrode in the feedback mode. The electrochemical feedback is ...
