Description

Description générale

Light green SF yellowish (LGSFY) is a disodium salt of an acid triphenylmethane dye. It is also known as Light Green, Lissamine Green SF, Food Green 2, Green No. 205, Acid Green, Acid Brilliant Green 5, and Acid Brilliant Green SF. LGSFY is an important component of Papanicolaou stains in addition to eosin Y and bismark brown Y. Light green SF yellowish is a histological stain for collagen and a permitted colorant for foodstuffs and beverages.

Application

Light green SF is generally used as a cytoplasmic counterstain with nuclear stains like safranine and Feulgen stain. In histopatology, it is used for collagen fiber staining in Masson′s trichrome, Papanicolaou cytological polychrome stains, and Twort stain for microorganisms in tissue sections. It is a constituent of polychrome staining method used for differentiating secretory cells of the pituitary gland. Light green SF also stains the cellulose cell walls of plant cells.
