Carboxyrhodamine 110 Azide
A green fluorescence-emitting probe with excitation/emission maximum of 501/523 nm.
The green-fluorescent azide is reactive with terminal alkynes via a copper-catalysed click reaction (CuAAC). It also reacts with strained cyclo-octyne via a copper-free “click chemistry” reaction to form a stable triazole and does not require Cu-catalyst or elevated temperatures. Carboxyrhodamine 110, also known as Rhodamine Green, a non-sulfonated analogue of Alexa Fluor 488® is a bright and exceedingly photostable green fluorescent label that can be used in place of Fluorescein, Alexa Fluor 488®, DyLight 488® and other dyes excitable at a wavelength of 488 nm.
