Electrophoresis, 18(14), 2582-2590 (1998-04-04)
Protein targeting and sorting is accomplished by complex vesicular transport processes that are tightly regulated within a cell. This is especially important for epithelial cells because correct delivery of newly synthesized proteins as well as recycling and sorting of internalized

Electrophoresis, 18(14), 2573-2581 (1998-04-04)
Electrophoretic techniques, and especially two-dimensional gel electrophoresis (2-DE), have provided an indispensable set of tools for the separation of complex protein mixtures as well as for the identification of protein-protein interactions. Nevertheless, after its introduction more than twenty years ago

The aqueous solutions of arsenous acid with the meso and racemic forms of 1,4-dithiol-butane-2,3-diol, namely, dithioerythritol (dte) and dithiothreitol (dtt), respectively, were titrated pH-metrically in different molar ratios. The p K a values determined for As(OH) 3, and dtt were

In this study, we describe the use of Tween 20-capped gold nanoparticles (AuNPs) as selective probes for the extraction of aminothiols from an aqueous solution. Tween 20 molecules noncovalently attached to the surface of AuNPs to form Tween 20-AuNPs were
