This product is lectin PNA labeled with our superior deep red fluorescent dye CF594. Lectin PNA is specific for terminal β-galactose and binds preferentially to a commonly occurring structure, galactosyl (β-1,3) N-acetylgalactosamine. CF594 (Ex/Em = 593/614 nm) is spectrally similar to Alexa Fluor? 594 and Texas Red? dye but yields much brighter protein conjugates due to its high quantum yield and exceptional water solubility. CF594 also has excellent photostability ideal for demanding applications, such as confocal microscopy and single molecule imaging. The dye is particularly useful to combine with our blue fluorescent CF350, green fluorescent CF488A and far red CF633 or CF647 for multi-color imaging.
