A new mechanism of selective transport and localization of proteins inside any living cell is presented. The mechanism is based on pH-induced protein trapping. It is shown that spontaneous and unique spatial redistribution of different proteins is possible in any aqueous solution with stable non-uniform distribution of H(+) ions. This phenomenon was(More)
A miniature electrophoretic device is developed on the basis of a new isoelectric focusing (IEF) method, namely parallel isoelectric focusing. We report here the theory and the results of operation of a new parallel isoelectric device (PID). The main advantages and limitations of the method are discussed for miniaturization purposes. It is shown that the(More)
A novel method for separation of low-molecular-mass heparins is reported here, on the basis of migrating the polyanionic heparins in a polycationic polyacrylamide gel, made by incorporating a gradient of positively charged monomers (the Immobilines used for creating immobilized pH gradients) into the neutral polyacrylamide backbone. Separations can be(More)
A new universal method for the generation of nonlinear electrophoretic mobility of a packet of any particles is suggested. The method is based on the investigation of particle packet dynamics under the influence of an external force. The system under consideration is a homogeneous and isotropic medium with traps for these particles. Packet dynamics is(More)
UNLABELLED The manuscript pages of the final draft of Master i Margarita, the masterpiece by Mikhail Bulgakov, written in the last four years of his life (1936-1940), have been treated with a mixture of chromatographic beads, namely a strong cation exchanger and a C8 resin. Potential substances captured by the beads, after harvesting them, were eluted with(More)
A novel method for separation of DNA fragments is here reported, based on migrating the polyanionic DNA fragments in a polycationic polyacrylamide gel, made by incorporating positively charged monomers (the Immobilines used for creating immobilized pH gradients) into the neutral polyacrylamide backbone. Separations can be operated under two working(More)
A miniaturized chemical sensor is here described for the analysis of environmental pollutants (VOC: volatile organic chemicals). It is used for remote detection of formaldehyde (FA) fumes in the atmosphere, and is based on the redox reaction between FA and silver nitrate. The sensor is worn as a bracelet and the data acquired are transferred via a Bluetooth(More)
Ten pages, selected from a total of 127, of the last manuscript of Master i Margarita, written by Bulgakov in the last four years of his life, have been analysed in order to harvest and identify any trace proteome left on the margin by the novelist, in the hope of finding biomarkers of his fatal nephrotic syndrome. To that aim, we prepared a special(More)
Investigation of isoelectric focusing (IEF) kinetics has been performed to provide the theoretical basis for miniaturization of classical IEF in immobilized pH-gradients. Standard IEF demands colinearity of the electric field and pH-gradient directions (serial devices). It is shown that the IEF separation process based on a continuous, serial pH gradient is(More)
