A method of staining polyacrylamide gels in which the dye is electrophoresed together with the sample is proposed. The method cuts short and simplifies the conventional electrophoresis procedure by eliminating the separate poststaining step. In the gels run in the presence of sodium dodecyl sulfate,

โฆ Synopsis
A method for the simultaneous staining of proteins during polyacrylamide gel electrophoresis with Coomassie brilliant blue R-250 at pH 2.5 is described. Calf thymus whole histone and cytochrome c were stained by this method and the results obtained were similar to that obtained by staining after electrophoresis.
