Rotavirus A causes severe diarrhoea in infants and young children worldwide. The migration pattern (electropherotype) of the double-stranded RNA genome upon polyacrylamide gel electrophoresis has been used to define "strains" in molecular epidemiology. In temperate countries, distinct electropherotypes (strains) appear after the annual, off-seasonal interruption of rotavirus circulation. In Nep...

The objective of the present study was to evaluate the effect of a nutritional intervention promoting the Mediterranean food pattern in free-living conditions on LDL electrophoretic characteristics in a group of seventy-one healthy women, aged between 30 and 65 years. The 12-week nutritional intervention consisted of two courses on nutrition and seven individual sessions with a dietitian. The f...

The recent trend in science is to assay as many biological molecules as possible within a single experiment. This trend is evident in proteomics where the aim is to characterize thousands of proteins within cells, tissues, and organisms. While advances in mass spectrometry have been critical, developments made in two-dimensional PAGE (2D-PAGE) have also played a major role in enabling proteomic...

A two-dimensional polyacrylamide gel electrophoresis technique is presented for separation of acid-extracted proteins of isolated nucleoli of normal rat liver and Novikoff hepatoma ascites cells. About 100 distinct protein spots were resolved. Comparison of the patterns for normal liver and Novikoff hepatoma revealed nine spots with markedly different intensities in the two patterns. Two spots ...

The number of proteins in rat liver ribosomes was determined by two-dimensional polyacrylamide gel electrophoresis. There were 30 proteins in the 40 S subunit, 39 in the 60 S subunit. The proteins of the two subunits, with one possible exception, are unique. Preparations of 80 S ribosomes contained three proteins not present in either subunit; thus, we estimate that eukaryotic ribosomes contain...

In nearly all cases, electrophoresis in gels is driven via the electrolysis of water at the electrodes, where the process consumes water and produces electrochemical by-products. We have previously demonstrated that π-conjugated polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT) can be placed between traditional metal electrodes and an electrolyte to mitigate electrolysis in liquid (capi...

A simple, rapid method is described for separating the serum lipoproteins into clear, discrete and reproducible bands by polyacrylamide disc gel electrophoresis. The sample is prestained with Sudan Black B in a sample gel and resolved by electrophoresis in a discontinuous pH system consisting of a sample gel, concentrating gel and separating gel. 30 young healthy males and 20 young healthy fema...

We describe a procedure for the convenient separation of proteins by sodium dodecyl sulfate/polyacrylamide gel electrophoresis of urine from cases of renal disease. A precipitation method that requires no special apparatus was used to concentrate the urinary proteins; for electrophoretic separation we used a commercially supplied polyacrylamide/cellulose gel slab. This method seems to be valuab...
