TAMRA (also known as TMR or tetramethylrhodamine) is a xanthene dye that has been used as a fluorescent label for decades. Xanthene dyes are available as two isomers (called 5- and 6-isomers) that have almost identical fluorescent properties, but need to be separated to avoid doubling and smearing of labeled product peaks or bands during chromatography or electrophoresis. This is a pure 6-isomer of TAMRA maleimide, used for the labeling of proteins and peptides via thiol (SH) groups.
TAMRA（也称为 TMR 或四甲基罗丹明）是一种呫吨染料，几十年来一直被用作荧光标记。 呫吨染料有两种异构体（称为 5 异构体和 6 异构体），它们具有几乎相同的荧光特性，但需要分离以避免在色谱或电泳过程中标记的产物峰或带加倍和拖尾。 这是 TAMRA 马来酰亚胺的纯 6 异构体，用于通过硫醇 (SH) 基团标记蛋白质和肽。
