We have simplified the highly sensitive silver stain of R. C. Switzer III, C. R. Merril, and S. Shifrin (1979, Anal. Biochem. 98, 231β237) for visualizing proteins in polyacrylamide gels. We have reduced the number of steps in the procedure from 10 to 6, simplified the reagents in each step, and red
Variations of the ultrasensitive silver staining method of B. R. Oakley, D. R. Kirsch, and N. R. Morris (Anal. Biochem. 105, 361-363 (1980)) have been tested. It was established that the reliability of the method was greatly improved if (i) free silver was carefully washed out before reduction with
