Lissamine rhodamine B PEG3 alkyne chemical and the commercial tetramethylrhodamine maleimides

and the commercial tetramethylrhodamine maleimides and iodoacetamides often have lower purities than other tetramethylrhodamine labeling reagents (such as TAMRA SE reagents) due to their synthetic difficulties

It has also been used to prepare various small fluorescent molecules

It is preferred for some complicated biological applications where reproducibility is critical since the minor positional difference between 5-isomer and 6-isomer might have biological implications

Lissamine rhodamine B PEG3 alkyne chemical and the commercial tetramethylrhodamine maleimidesSulforhodamine B PEG3 alkyne (Lissamine rhodamine B PEG3 alkyne) is an excellent azide reactive fluorescent reagent for labeling azide containing biological molecules through click chemistry. The conjugate has better solubility than the parent dye carboxyrhodamine and its long PEG spacer should reduce any steric effect of the dye on the molecule to be labelled. The fluorescence emission spectrum of Lissamine rhodamine B lies between those of
