Bella Fluor 488 Alkyne is a green-fluorescent dye that is reactive with azide moieties using a copper-catalyzed click reaction. Click chemistry is favored for labeling and detection of target molecules because the highly selective labeling reaction is fast and efficient with few side products, requires no special solvents or temperatures, and yields a stable linkage between the target and the label. This single-isomer, alkyne analog of our BF 488 is ideal for imaging, HCS, and flow cytometry applications where label brightness and photostability are critical. Bella Fluor 488 is relatively environmentally insensitive and insensitive to pH changes between pH 4 and pH 10. Bella Fluor 488 is optimally excited by a 488 nm laser line, water soluble and brightly fluorescent in aqueous solvents. .
