Concanavalin A (Con A) is one of the most widely used lectins in cell biology. Our Alexa Fluor® 594 conjugate of Con A exhibits the bright, red fluorescence of the Alexa Fluor® 594 dye (absorption/emission maxima ~590/617 nm). Alexa Fluor® 594 Con A selectively binds to a-mannopyranosyl and a-glucopyranosyl residues.
