AZDye™ 405 Azide can be reacted 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.
AZDye™ 405 is a bright, blue-fluorescent probe optimally excited by the 407 nm spectral line of the krypton laser or the 408 nm violet laser diode. This probe is water-soluble and its fluorescence is pH independent over a wide pH range. The brightness and photostability of this dye are best suited to direct imaging of moderate-abundance targets.
AZDye™ 405 is structurally similar to Alexa Fluor® 405 or Cascade Blue, and spectrally is a match to DyLight® 405, Alexa Fluor® 405, CF® 405S Dye, Cascade Blue, or any other sulfonated pyrene based fluorescent dyes.
