ROX is a bright rhodamine dye with emission maximum around 580 nm. It is widely used for the labeling of biomolecules. As other rhodamine dyes, it comes as two isomers, 5-ROX and 6-ROX. Although these isomers have almost identical spectral properties, they need to be separated to avoid doubling of labeled products on HPLC or electrophoresis.

This derivative contains thiol-reactive maleimide moiety for the attachment of ROX fluorophore to SH groups, such as cystein residues in proteins and peptides.

ROX 是一种明亮的罗丹明染料,最大发射波长约为 580 nm。 它广泛用于标记生物分子。 与其他罗丹明染料一样,它有两种异构体,5-ROX 和 6-ROX。 尽管这些异构体具有几乎相同的光谱特性,但需要将它们分离以避免在 HPLC 或电泳中标记产物加倍。

该衍生物含有硫醇反应性马来酰亚胺部分,用于将 ROX 荧光团连接到 SH 基团,例如蛋白质和肽中的半胱氨酸残基。
