Carboxyrhodamine 110 Azide

5(6)-Carboxyrhodamine 110 Azide (also known as Rhodamine Green) is photostable, green-fluorescent probe that reacts with terminal alkynes via a copper-catalyzed click reaction (CuAAC). It also reacts with strained cyclooctyne via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures.

5(6)-Carboxyrhodamine 110 (also known as Rhodamine Green) is the nonsulfonated analog of the Alexa Fluor® 488 dye with excitation/emission maxima ~502/527 nm. Carboxyrhodamine 110 is bright photostable and pH-insensitive from pH 4 to pH 10 dye. This probe can be used with the 488 nm line of argon-ion laser and standard FITC filter set.
