AFDye™ 405 Cadaverine (Alexa Fluor® 405 Cadaverine equivalent) is a carbonyl-reactive building block used to modify carboxylic groups in the presence of activators (e.g. EDC or DCC) or activated esters (e.g. NHS esters) through a stable amide bond. Another common application for AFDye™ 405 Cadaverine is cell fixing by treatment with formaldehyde or glutaraldehyde.
AFDye™ 405 is a water-soluble, blue-fluorescent dye that is often used in multi-color applications, including flow cytometry and super-resolution microscopy using STORM. Its excitation is ideally suited for the 407 nm spectral line of the krypton laser or the 408 nm violet laser diode. AFDye™ 405 is structurally and spectrally similar to DyLight® 405, Alexa Fluor® 405, CF® 405S Dye, or any other pyrene-based fluorescent dyes.
