TAMRA (tetramethylrhodamine) is a xanthene dye of rhodamine series. This fluorophore is being used for quite a long time for the preparation of dual labeled qPCR TaqMan oligonucleotide probes containing TAMRA and fluorescein (FAM).

Just like many other xanthene fluorophores, TAMRA is a available as two isomers (5- and 6-isomer) which have nearly identical optical properties. This product is an isomerically pure 5-TAMRA.

TAMRA NHS is an amine reactive reagent. It can be used for the labeling of proteins, peptides, and modified oligonucleotides containing amine groups.

TAMRA(四甲基罗丹明)是罗丹明系列的呫吨染料。 这种荧光团用于制备含有 TAMRA 和荧光素 (FAM) 的双标记 qPCR TaqMan 寡核苷酸探针已经有很长时间了。

就像许多其他呫吨荧光团一样,TAMRA 可作为两种异构体(5-和 6-异构体)获得,它们具有几乎相同的光学特性。 该产品是异构纯的 5-TAMRA。

TAMRA NHS 是一种胺反应试剂。 它可用于标记蛋白质、肽和含有胺基的修饰寡核苷酸。
