Coomassie-Stained Protein Gel Destaining: Rapidly removes Coomassie dye from SDS-PAGE gels to enhance band visibility and contrast.

Protein Fixation in Polyacrylamide Gels: The 45% Methyl Alcohol, 9% Acetic Acid composition fixes proteins, minimizing diffusion prior to imaging or drying.

Background Reduction for Gel Imaging: Lowers nonspecific background to improve sensitivity on gel documentation systems.

Pre-/Post-Stain Gel Washes: Used to equilibrate and wash gels before and after staining to achieve consistent results.

Preparation for Silver Staining: Serves as a fixation step prior to silver staining workflows to stabilize proteins in-gel.

In-Gel Digestion Preparation: Assists in initial destaining of Coomassie-stained bands before proteolytic digestion and mass spectrometry.

Cleaning Staining Equipment: Helps remove Coomassie dye residues from trays, containers, and glassware.
