一般說明
番红O，也称碱性红2，是一种碱性、阳离子和变色偶氮染料，用作生物染色剂。它特有的偶氮发色团包含吩嗪，这是一种平面三环二苯并吡嗪，由两个非平面苯环通过两个氮原子连接而成。发色团系统包括离域的正电荷、芳香和醌型结构的交替以及可重氮化的胺基。c-甲基化使该染料具有适中的整体尺寸。 番红的三甲基阳离子形式是亲脂性的，而二甲基形式是弱亲水性的。该染料市售形式为氯化物。
應用
- 番红 O被广泛用作微生物染色剂，特别是在革兰氏染色中 用作复染剂，以区分革兰氏阳性菌和革兰氏阴性菌， 并用于染色细菌孢子。
- 它用于显示人类和动物组织标本中的 糖胺聚糖和细胞核。
- 它是Benda复色染料的成分。
- 它是各种复色和木质素染色剂中用于植物染色应用的 成分。
- 它还已应用于细胞涂片制备中 肥大细胞的显示和外科冷冻切片的染色。
