5-CR110 [5-Carboxyrhodamine 110] *Single isomer*

Descrition & Target

5-CR110-PEO₃-amine has a long water-soluble PEG spacer that separates the green fluorescent CR110 and the amine functional group. <ul> <li>&lamba;_Ex/&lamba;_Em(MeOH) = 502/524 nm</li> <li>Orange yellow solid soluble in DMSO, DMF, or H2O</li> <li>Store at -20°C and protect from light</li> <li>C₃₃H₃₄F₆N₄O₁₁</li> <li>MW: 776.63</li> </ul>

Descrition & Target

5-CR110-PEO₄ SE (full name: 5-Carboxyrhodamine 110-PEO₄-propionate, succinimidyl ester, single isomer) is an excellent green fluorescent rhodamine dye for labeling amines. The dye has better solubility than the parent dye 5-CR110 SE and its long PEG spacer should reduce any steric effect of the dye on the molecule to be labeled. Carboxyrhodamine 110 and its derivatives are, in general, significantly more photostable than any other known green fluorescent dyes including Alexa Fluor&reg; 488. In addition, their spectra are unaffected by pH change from 4 to 9. Unlike Alexa Fluor&reg; 488, which is readily degraded under alkaline conditions, CR110 and its derivatives are highly stable under both acidic and basic conditions. As a result, CR110 and its derivatives are superior alternatives to other green fluorescent dyes for applications where only a single dye is required for the labeling. <ul> <li>&lamba;_Ex/&lamba;_Em(MeOH) = 502/524 nm</li> <li>Orange red solid soluble in DMF or DMSO</li> <li>Store at -20°C and protect from light</li> <li>C₃₆H₃₈N₄O₁₂</li> <li>MW: 718.71</li> </ul>

5-CR6G [5-Carboxyrhodamine 6G] *Single isomer*

Descrition & Target

5-CR6G, SE [5-Carboxyrhodamine 6G, succinimidyl ester] *Single isomer*

Descrition & Target

This dye can be used as a low pH indicator similar 5-and-6-Carboxy-2'7'-dichlorofluorescein, and is also useful as a general green fluorescent label. Carboxy-2',7'-dichlorofluorescein is significantly more photostable than carboxyfluorescein.

Descrition & Target

The pKa of 5-carboxy-2',7'-dichlorosulfonefluorescein is near 4 and thus the dye is potentially an excellent pH indicator for acidic organelles.
