AFDye™ 488 Picolyl Azide is an advanced fluorescent probe that incorporates a copper-chelating motif to raise the effective concentration of Cu (I) at the reaction site to boost the efficiency of the CuAAC reaction, resulting in a faster and more biocompatible CuAAC labeling. Up to 40-fold increase of signal intensity, compared to conventional azides, was reported (see Selected References).

AFDye 488 has green fluorescence that is pH independent from pH 4 to pH 10 with excitation ideally suited for the 488 nm laser line. EXTINCTION COEFFICIENTS AND FLUORESCENCE DATA Calculate extinction coefﬁcient of an oligo by either summing up the extinction coefﬁcients of the individual bases times their number of occurrences. Or use a formula that takes into account nearest neighbor effects. An algorithm for this calculation can be found on the web. Just AFDye™ 488 is a bright, highly photostable, green-fluorescent probe optimally excited by the 488 nm laser line.

31. ATTO 532. 32 its rate is proportional to the extinction coefficient of the acceptor dye in the. One of the most useful quantitative parameters for characterizing absorption spectra is the molar extinction coefficient denoted with the Greek symbol ε.
