说明

结晶紫用作革兰氏染色的活性成分，主要染色剂，用于革兰氏阴性菌与革兰氏阳性菌的分化。它是具有亲脂性阳离子的六-N-甲基化三氨基三苯甲烷。它具有略微非平面的共轭系统。
结晶紫通常用于革兰氏染色及其变体；并染色淀粉样蛋白，细菌成分和维管植物组织。它也用于植物染色体的染色。结晶紫也适用于琼脂糖凝胶中的DNA可视化。该染料仅在高浓度DNA存在下使用。结晶紫还有助于细胞活力的比色测量。

一般描述

Crystal violet is used as an active component, primary stain, of Gram stain for differentiation of Gram-negative versus Gram-positive bacteria. It is a hexa-N-methylated triaminotriphenylmethane with a lipophilic cation. It possesses a slightly nonplanar conjugated system.
 

应用

Crystal violet is commonly used in the Gram stain and its variants; and to stain amyloid, bacterial components, and vascular plant tissues. It is also used for the staining of plant chromosomes.Crystal violet is also suitable for DNA visualization in agarose gels. The dye is used only in the presence of high concentrations of DNA. Crystal Violet also helps in the colorimetric measurement of cell viability.
