一般描述

溴百里酚蓝,又称为二溴百里酚磺酞,是酸性水溶液中的磺化羟醌。在碱性溶液中,这种染料以中等大小的离子形式存在。它也被称为溴百里酚蓝和二溴百里酚磺酞。它是一种pH值敏感的染料,可从黄色变成蓝色。

应用

溴百里酚蓝染料具有精确的中性颜色过渡,因此可作为 pH 指示剂。 其他应用包括:
  • 作为重要染色剂,用于在显微镜下跟踪淋巴液运动并界定细胞壁或细胞核
  • 用于展示植物根内的真菌菌丝
  • 评估单粒水稻的可溶性酸度
  • 用于琼脂凝胶培养基中蜡样芽孢杆菌的计数
  • 作为几种细菌生长和检测底物的组分,如胱氨酸乳糖电解质缺乏(CLED/BROLACIN);丙酮酸多粘菌素蛋黄甘露醇溴百里酚蓝(PEMBA)和麦康基琼脂。
