Synonyms: 5--carboxyrhodamine 110 azide

Functional Activity:

Single isomer. 5-CR110 azide is an excellent alkyne-reactive fluorescent reagent for labeling azide-containing biological molecules through click chemistry. Its excitation maximum (at 501 nm) matches the intense 488 nm spectral line of the argon ion laser commonly used in many confocal laser-scanning microscopes. Carboxyrhodamine 110 and its derivatives are, in general, signi?cantly more photostable than any other known green ?uorescent dyes including Alexa 488. In addition, the ?uorescence of the product is completely insensitive to pH between 4 and 9. Unlike Alexa 488, which is readily degraded under alkaline condition, carboxyrhodamine 110 and its derivatives are highly stable under both acidic and basic conditions. As a result, carboxyrhodamine 110 and its derivatives are superior alternatives to other green ?uorescent dyes.
