BAM R3: Basic Fuchsin Staining Solution
Dissolve 0.5 g basic fuchsin dye in 20 ml 95% ethanol. Dilute to 100 ml with distilled water. Filter if necessary with Whatman No. 31 filter paper to remove any undissolved dye. (TB Carbolfuchsin ZN staining solution, available from Difco Laboratories, is satisfactory.)
