酸性黑1 1064-48-8 Amido black 10B

应用：

可溶于水，呈蓝黑色。溶于酒精呈蓝色，微溶于丙酮，不溶于其他有机溶剂。遇浓硫酸呈蓝光绿色，将其稀释后生成暗绿色光的蓝色沉淀；遇浓硝酸呈暗绿色溶液，后转变为酱红色；遇10%氢氧化钠溶液呈艳蓝色。其水溶液加浓盐酸生成绿光蓝色沉淀，加氢氧化钠液生成蓝色沉淀。染色时，遇铜、铁离子，其色泽前者微有变化，后者略带浅绿.

萘酚蓝黑已被用于蛋白质印迹膜的染色，可用于检测转移至膜的所有蛋白质。用于对聚丙烯酰胺凝胶、琼脂糖凝胶和硝酸纤维素膜上蛋白质的染色。在电泳后，推荐固定蛋白质在胶上。 胶用 0.1% 氨基黑10B的7% (v/v) 醋酸溶液染至少2 小时，然后用7% (v/v) 醋酸溶液脱色。检测灵敏度大概是考马斯亮蓝R250的20%.
