A Simple, Time-Saving Dye Staining of Proteins in Sodium Dodecyl Sulfate-Polyacrylamide Gel Using Coomassie Blue.

Most traditional post-electrophoretic processes need several hours to several days to finish the whole staining process and traditional staining solutions all contain methanol, acetic acid, or phosphoric acid, which not only produce the unpleasant smell but also cause environmental pollution. Here a fixation-free, fast protein staining method in sodium dodecyl sulfate-polyacrylamide gel electrophoresis using Coomassie blue is described. The protocol includes only staining and quick washing steps, can be completed in 0.
