TAMRA-PEG3-biotin linker contains a TARMA dye and a DBCO group, which enables Click Chemistry. The TAMRA dye has achieved prominence as a dye for oligonucleotide labeling and automated DNA sequencing applications. DBCO readily reacts with azide functionalized compounds or biomolecules without catalyst to form a stable triazole linkage, which is an ideal alternative to copper intolerant applications. The PEG spacer increases the aqueous solubility of the resulting compound.
