Cation dye. Used in Gram staining to distinguish between gram positive and negative bacteria. Interacts with aqueous form of Kl-I2 during gram staining producing a chemical precipitate. Displays colour changes at different pHs (pH0.0- yellow, pH 2.0- blue/violet). Also used to measure Cytostatic/cytotoxic effects on tumour cell lines.
Prepare and use solutions on the same day if possible. Store solutions at -20°C for up to one month if storage is required. Equilibrate to RT and ensure the solution is precipitate free before use.
