Here we set forth the first from a series of reports devoted to history capillary electrophoresis. In this opening part, go more than two centuries back in time and revisit original discoveries electrolysis, electrophoresis electroosmosis. We emphasize essential role brilliant invention 1799 by Alessandro Volta, Voltaic pile, basically battery delivering constant-flow electricity, which has mad...

we have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-de). this modified version of 2-de is not only simpler and easier but also faster than all the currently available methods. in this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-...

This study examines a sharp decline of school attendance among white children in the Southern US after the Civil War. According to Census data, the school-attendance rate among whites in the Confederate states declined by almost half from 1860 to 1870, whereas that in the Northern states was approximately stable. This shock left the South approximately three decades behind its antebellum trend....

The movement of macromolecules in cells is assumed to occur either through active transport or by diffusion. However, the determination of the diffusion coefficients in cells using fluctuation methods or FRAP frequently give diffusion coefficient that are orders of magnitude smaller than the diffusion coefficients measured for the same macromolecule in solution. It is assumed that the cell inte...

background : glioblastoma multiforme (gbm) or grade iv astrocytoma is the most common and lethal adult malignant brain tumor. several of the molecular alterations detected in gliomas may have diagnostic and/or prognostic implications, proteomics has been widely applied in various areas of science, ranging from the deciphering of molecular pathogen nests of discuses. method: we extracted protein...

alpha-amylase e.c.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as pseudomonas and asperigllus, as well as muscles and ovarian tubes.1.2 alpha-amylase from bacillus subtilis #1024(a tcc 465)* was purified with a highest degree of purity in our laboratory (31.59 u/mg). the extracellular alpha-amylase was subjected to different pu...
