一般描述
在高纯度中制备的重要荧光基团，通过约 600 个分子的毛细管电泳检测限为 TMR 标记氨基酸。容易被荧光显微镜中使用的汞弧灯的 546 nm 光谱线激发，本质上比荧光素更具光稳定性。
应用
5-羧基四甲基罗丹明已用于荧光团表征。
生化/生理作用
5-羧基四甲基罗丹明可以共价连接到 DNA 上，从而用于涉及分支和双链 DNA/RNA 结构的研究。主要用于单分子研究。5-羧基四甲基罗丹明也用于标记寡糖，用于激光诱导荧光检测。

Iron oxide nanostructures have been widely developed for biomedical applications because of their magnetic properties and biocompatibility. In clinical applications, stabilization of these nanostructures against aggregation and nonspecific interactions is typically achieved using weakly anchored polysaccharides, with better-defined and more
