Tamra is a Carboxytetramethylrhodamine, a derivative of rhodamine. Tamra represents an excellent alternative to NED and it is commonly used in FRET and real time applications. 5-Tamra-Azid is an azide modifier that can be used in Click-Chemistry. This technique allows multiple alkynated multiple sites within an oligonucleotide to be labelled by “clicking” a variety of azide-containing labels/tags.
