Iodine green is a nuclear or chromatin stain which has selective properties that make it of value in certain special procedures. It is used by Ciaccio for nervous tissue in combination with acid fuchsin and picric acid; and by Lefas as a blood stain in combina- tion with acid fuchsin. It is used by Zimmermann with basic fuchsin for staining chromatin in plant tissue; while together with acid fuchsin it is occasionally used by botanists for staining lignified xylem. It is also used for staining mucin and amyloid, having the property of giving the latter a red instead of a green color. SPIRIT BLUE C. I. NO. 689 Synonyms: Gentian blue.
