Capillary zone electrophoresis and carrier ampholytes based capillary electrophoresis have been used as a second separation step to Off-Gel isoelectric focusing for the analysis of complex peptide mixtures. A tryptic digest of four proteins (bovine serum a ...
We report the detection of protein molecules with nanofabricated pores using the resistive pulse sensing method. A 20-nm -thick silicon nitride membrane with a nanofabricated pore measuring about 55 nm in diameter separated an electrolyte cell into two com ...
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 ...
Mesenchymal cells in the developing pancreas express the neural stem cell marker nestin and the transcription factor islet-1 (Isl-1). Using defined culture conditions we isolated on a single cell basis nestin producing cells from human pancreatic islets. T ...
In a survey of cardiovascular risk factors in 185 men and 173 women of a Belgian population group, an independent and highly significant positive correlation was found between the serum concentrations of 25-hydroxyvitamin D3 and apolipoprotein A-I (p less ...
An efficient strategy for visualizing human fingerprints on a poly(vinyldene difluoride) membrane (PVDF) by sanning electrochemical microscopy (SECM) has been developed. Compared to a classical ink fingerprint image, here the ink is replaced by an aqueous ...
Zaragozic acids (or squalestatins) are very potent inhibitors of squalene synthase. They or simpler analogs have potential as drugs for lowering the endogenous level of cholesterol in human serum. These compounds are Ras farnesyltransferase inhibitors and ...
Densely crosslinked semi-interpenetrating polymer networks (semi-IPNs) of poly(ethylene glycol) (PEG) were synthesized by photopolymerizing a melt of PEG of various molecular weights and end-group functionalities in neat trimethylolpropane triacrylate (TMP ...
The attachment, spreading, spreading rate, focal contact formation, and cytoskeletal organization of human umbilical vein endothelial cells (HUVECs) were investigated on substrates that had been covalently grafted with the cell adhesion peptides Arg-Gly-As ...
Magnetic resonance spectroscopy (MRS) measurements of the lactate methyl proton in rat brain C6 glioma tissue acquired in the presence of an off- resonance irradiation field, analyzed using coupled Bloch equation formalism assuming two spin pools, demonstr ...
