β¦ Synopsis
A specially designed apparatus and conditions are described for the rapid analysis of ribosomal proteins by two-dimensional gel electrophoresis on a micro scale. The resolution of proteins in electropherograms is comparable to that obtained with other systems, but because of miniaturization, only 0.5 to 1 mug of each protein is required, and the entire procedure, including electrophoresis in both dimensions, and staining and destaining can be completed in 6 to 7 hours.

Proteins from mitochondrial ribosomes of Saccharomyces cerevisiae were analysed by a two dimensional gel electrophoresis method. Each ribosomal subunit revealed a reproducible characteristic pattern of protein components. The 37S small subunit contained 33 protein species with an average molecular w
The 80S ribosome of Schizosaccharomyces pombe contains 93 proteins as determined by twodimensional electrophoresis on polyacrylamide gels. Of these, 76 are basic and 17 are acidic at pH 8.7. 38 proteins could be assigned unambiguously to the large sub-unit and 19 to the small. 67 proteins were extra
