APDye Fluor 647 Amine is structurally similar to Alexa Fluor® 647 and spectrally nearly identical to Cy5 Dye, Alexa Fluor® 647, CF® 647 Dye or any other Cyanine5-based fluorochrome. APDye 647 Amine is a water-soluble, bright, far-red fluorescent dye with excitation light well suited for 633 nm or 647 nm laser lines. APDye 647 Amine is a carbonyl reactive building block used to modify carboxyl groups through stable amide linkages in the presence of activators such as EDC or DCC or activated esters such as NHS esters.
