Alexa Fluor 488 is a bright, green fluorescent dye with excitation ideally suited to the 488 nm laser line. Used for stable signal generation in imaging and flow cytometry, Alexa Fluor 488 dye is water soluble and pH-insensitive from pH 4 to pH 10. A large number of rhodamine dyes, including Alexa Fluor 488, Alexa Fluor 532, Alexa Fluor 568, ATTO488, ATTO532, and ATTO565, were found to form stable radical anions upon irradiation in the presence of thiol compounds such as β-mercaptoethylamine (MEA). 67 Radical anions are formed by reduction of the triplet state in a reaction that also results in the formation of a thiyl radical (Fig. 1.10). AFDye™ 488 Alkyne (Alexa Fluor® 488 Alkyne equivalent) is a bright, green-fluorescent, alkyne-activated probe routinely used for imaging of low abundance azide-containing biomolecules. AFDye™ 488 Alkyne reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker.

In contrast, S65T and EGFP extinction coefficients made them both approximately 6-fold brighter than wtGFP when excited at 488 nm, and EBFP absorbed more strongly than the wtGFP when excited in the near-UV wavelength region, although it had a much lower quantum efficiency.

To request additional information and datasets for Alexa Fluor 488, please contact info@aatbio.com. Unless otherwise specified, molar extinction coefficient (ε) values are typically measured in ddH2O or PBS. where 71,000 cm-1M is the approximate molar extinction coefficient of the Alexa Fluor® 488 dye at 494 nm. For IgGs, we find that labeling with 4–9 moles of Alexa Fluor® 488 dye per mole of antibody is optimal.

In -20°C or -70°C serum can usually be stored for years, but in some specific cases, this time may be shorter for anti-peptide antibodies. Use the extinction coefficient (ɛ) of rhodamine B (ɛ 555 = 106,000) to determine the concentration of the rhodamine B solution. The concentration of the stock solution measured in the experiments presented here is 4.3 μM. 2.
