Methyl Blue 1 %, aqueous

Methyl blue 1 %, aqueous is a staining solution used in histology and cytology. Methyl blue is a basic dye that binds to acidic tissue components. The aqueous solution provides a mild environment for use in the staining process and allows precise control over staining.

In histology, methyl blue is commonly used in Mallory-Heidenhain staining, in which methyl blue is used in combination with azo arms and aniline blue. This staining technique allows the visualization of connective tissue, muscle tissue and cytoplasm in different colors. Here, methyl blue stains cytoplasm and mucus in blue tones.
