Resolution of Bacterial Proteins by Polyacrylamide Gel Electrophoresis on Slabs
The application of a method of electrophoretic protein analysis to the investigation of the total protein composition of Salmonella typhimurium is described. It involves electrophoresis of many samples simultaneously on a thin slab of acrylamide gel, in the presence of sodium dodecyl sulfate, with the discontinuous buffer system of Laemmli ((19’70) Nature 227, 680485). Up to about 25 samples ca...
متن کاملDetection of lipopolysaccharides by ethidium bromide staining after sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
A rapid and easy method for staining lipopolysaccharides with ethidium bromide is described. Lipopolysaccharides could be visualized by ethidium bromide with almost the same sensitivity as found with the silver-staining method in less than 30 min. The ethidium bromide-staining method was particularly suitable for staining lipopolysaccharides possessing acidic O-specific polysaccharides, which w...
متن کاملPolyacrylamide Gel Electrophoresis
Polyacrylamide gels are typically formed by polymerization of the monomer acrylamide crosslinked to the co-monomer, N,N’-methylenebis-acrylamide, commonly called BIS. This process is a freeradical polymerization that requires an initiator, usually ammonium persulfate, and a catalyst like N,N,N’,N’-tetraethylmethylenediamine (TEMED). A distinct advantage of polyacrylamide gel systems is that by ...
متن کاملNeutral polyacrylamide gel electrophoresis.
MATERIALS 5x TBE electrophoresis buffer Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8 V/cm) to prevent denaturation of small fragments of DNA by Joulic heating. Other electrophoresis buffers such as 1x TAE (please see Agarose Gel Electrophoresis) can be used, but they are not as good as TBE. The gel must be run more slowly in 1x TAE, which does not provide as much...
متن کاملCharacterization of Wolinella spp., Campylobacter concisus, Bacteroides gracilis, and Eikenella corrodens by polyacrylamide gel electrophoresis.
The small asaccharolytic, nonpigmenting gram-negative rods of the human oral cavity are difficult to differentiate from each other. Protein profiles of sonicated cells of Wolinella species, Campylobacter concisus, Bacteroides gracilis, and Eikenella corrodens were obtained by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and visualized with a silver stain. The gels were scanned with...
