molarity: A / ε. molar = molar concentration . However, many sources, including the reference cited above, do not provide molar extinction coefficients. Instead AFDye™ 488 DBCO (Alexa Fluor® 488 DIBO analog) is a water-soluble, green-fluorescent probe for copper-less detection of azide-tagged biomolecules. In application where the presence of copper is a concern AFDye™ 488 DBCO is an ideal alternative to copper requiring fluorescent alkynes.

Optical Data for TFAX 488, SE Emission Color 2 days ago Excitation maximum = 495 nm; emission maximum = 515 nm; extinction coefficient = 73,000 M-1 cm-1; quantum yield = 0.92.

Azide-fluor 488 ≥90% (HPLC) Synonym: Rhodamine 110-azide Empirical Formula (Hill Notation) C 29 H 30 N 6 O 7. Molecular Weight 574.58 . NACRES NA.22 . SDS AFDye™ 488 (Alexa Fluor® 488 equivalent) is a bright, highly photostable, green-fluorescent probe optimally excited by the 488 nm laser line. This probe is water-soluble and its fluorescence is pH independent over a wide pH range. The brightness and photostability of AFDye™ 488 dyes are best suited to direct imaging of low-abundance targets.
