High-temperature sodium dodecyl sulfate polyacrylamide gel electrophoresis.
The run time for sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) can be reduced to as little as 5 min by running vertical slab gels at 70°C. High-temperature SDS-PAGE increases the migration rate of protein bands several fold and is as effective as cooling in preventing uneven migration rates across the width of the gel. Additional benefits of hightemperature SDS-PAGE inclu...
متن کاملAnalysis of the subunit structure of protochlorophyllide holochrome by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
The subunit structures of protochlorophyllide holochrome (PCH) and chlorophyllide holochrome (CH) were studied by sodium dodecyl sulfate (SDS)-polyacrylamide gel electrophoresis. PCH from leaves of dark-grown (Phaseolus vulgaris var. red kidney) is a polymeric pigment-protein complex of approximately 600,000 daltons. It is composed of 12 to 14 polypeptides of 45,000 daltons, when examined prior...
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 کاملA recommendation for visualizing disulfide bonding by one-dimensional sodium dodecyl sulfate--polyacrylamide gel electrophoresis.
A simple modification of the conventional one-dimensional sodium dodecyl sulfate--polyacrylamide gel electrophoresis technique has been used to visualize inter- and intramolecular disulfide bonding in proteins. The gradient of reducing agent established between adjacent slab gel tracks by electrophoresing identical protein samples next to one another, one containing and the other not containing...
متن کاملPresumptive fecal streptococci in environmental samples characterized by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis.
The use of fecal streptococci as fecal indicators requires better knowledge of the ecology of these bacteria. We isolated 371 presumptive fecal streptococci from environmental samples--domestic wastewater, forest industry wastewater, contaminated surface and seawater, well water, cow dung, bird droppings, and pristine waters--and clustered them according to their protein profiles in one-dimensi...
