| Abstract: | The molecular weights of the proteins from rabbit liver ribosomal 40 S and 60 S subunits were determined after preliminary separation of these proteins by two-dimensional electrophoresis: each spot present in the polyacrylamide slab was cut off, eluted and rerun in a SDS one-dimensional polyacrylamide gel. The molecular weights range from 9,000 to 35,000 with a number-average molecular weight of 19,600 for the 40 S proteins, and from 9,400 to 52,000 with a number-average molecular weight of 23,600 for 60 S proteins. |
