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; _Ex/&lamba; _Em (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>C₃₁H₃₀N₄O₆</li> <li>MW: 554.59</li> </ul>
