磺酰罗丹明 B (SRB) 是一种荧光蛋白染料。 据报告，染料在温和的碱性条件下与三氯乙酸固定细胞的氨基酸残基结合，并在温和的酸性条件下将其自身提取到溶液中。 最大吸收波长： 558 nm 产品应用： SRB 对其对活细胞反应性的 pH 敏感性使其可用于药物诱导的细胞毒性和细胞增殖。SRB 实验用于监测活细胞的酶活性。 Description Sulforhodamine B (SRB) is a fluorescent protein dye. It was reported that the dye binds itself to the amino acid residues of tricholoroacetic acid fixed cells in mild basic conditions and extracts itself into the solution under mild acidic conditions.pH sensitive of SRB towards it reactivity to living cells renders it useful for scaling drug induced cytotoxicity and cell proliferations. SRB assay was used to monitor the enzymatic activity of living cells.
