Bella Fluor 488 5(6)-carboxylic acid is a mixed isomer, carboxylate analog of our green-fluorescent Bella Fluor 488 dye that is ideal for imaging and flow cytometry applications where label brightness and photostability are critical. Bella Fluor 488-carboxylic acids are reactive with primary amines on peptides, proteins, modified nucleotides, biopolymers and other amine containing biomolecules when used with a coupling agent like the water soluble carbodiimide, EDAC. Bella Fluor 488 is optimally excited by a 488 nm laser line, water soluble and brightly fluorescent in aqueous solvents. .
