This product is lectin PNA labeled with our superior far-red fluorescent dye CF640R. Lectin PNA is specific for terminal β-galactose and binds preferentially to a commonly occurring structure, galactosyl (β-1,3) N-acetylgalactosamine. CF640R dye (Ex/Em = 642/662 nm) is brighter and far more photostable than Alexa Fluor? 647 when excited by the 633 or 635 nm laser, making CF640R Annexin V an excellent choice for both flow cytometry and microscopy applications (download the CF640R Flyer for more information).
