4-Sulforhodamine 101 cadaverine, trifluoroacete salt
Descrition & Target
Cyanine NS succinimidyl esters are non-sulfonated cyanine dyes that can be used to label proteins, oligonucleotides and nucleic acids. Available in 3 colors, Cyanine 488NS, Cyanine 555NS, and Cyanine 647NS are non-sulfonated versions of Cy®2, Cy®3, and Cy®5, respectively. They are designed to match by charge and molecular weight for 2D DIGE platform. 9689c5aa-6556-4b3c-b5d1-1e693715ba07 offers these dyes as high quality amine-reactive succinimidyl esters.

5(6)-CARBOXYRhodamine 110-C5-MALEIMIDE (
Descrition & Target
CR110-C5-maleimide (full name: 5(6)-Carboxyrhodamine 110-C5-maleimide) is a maleimide derivative of the green fluorescent dye carboxyrhodamine 110. The dye has spectral properties (&lamba; <sub>Ex</sub>/&lamba; <sub>Em</sub> (MeOH) = 502/524 nm) similar to those of fluorescein (fluorescein-5-maleimide, for example), but the photostability of the dye is among the best of all green fluorescent dyes. Thus, the dye is a superior green fluorescent dye for labeling thiols. <ul> <li>Orange red solid soluble in DMF or DMSO</li> <li>Store at -20°C and protect from light, especially in solution</li> <li>C<sub>31</sub>H<sub>30</sub>N<sub>4</sub>O<sub>6</sub></li> <li>MW: 554.59</li> </ul>

5(6)-CFDA (5-(And-6)-Carboxyfluorescein
Descrition & Target
5(6)-CFDA (full name: 5-(and-6)-Carboxyfluorescein diacetate) is membrane-permeant and thus can be loaded into cells via incubation. Once inside cells, CFDA is hydrolyzed by intracellular esterases to carboxyfluorescein.
