Dilute sample 10-fold with labeling buffer INTRODUCTION Coomassie brillant blue R250 (CBR-250) and silver staining are the most widely used methods for the routine visualization of proteins separated by SDS-PAGE. In order to visualize this protein standard, a process of staining the gel in a different Coomassie than the one used in this protocol is required (e.g. This stains the entire gel, not just the proteins. The protocol involves soaking the gel in a dye solution . in the next step, gels are boiled for 2 min in the staining solution (0.05% coomassie blue g in water) and destained with a 4 mm edta (disodium salt) solution at a boiling temperature until a transparent gel background is achieved (approximately 50 to 60 min); it is of critical importance to keep the washing solution at or just below the boiling provide the researcher with an efficient staining method and a dynamic range of 5-500ng, which is ~10 times more sensitive than traditional coomassie R-250-based dyes. 3. The gel should be exposed to 10% acetic acid, 50% methanol for a total (stain plus destain) period of at least 3 hours (with shaking and at least three solvent . Due t.
