Application

5-([4,6-Dichlorotriazin-2-yl]amino)fluorescein hydrochloride has been used for labeling of yeast cells to study the adhesion of yeast cells to the digestive tract of sea bass (Dicentrarchus labrax) larvae and leopard grouper (Mycteroperca rosacea). It has also been used to label bacteria (Vibrio spp.).
5-([4,6-Dichlorotriazin-2-yl]amino)fluorescein hydrochloride has been used to covalently label xanthan gum (XG) to study its gelatin behavior.
