A fluorescent technique has been developed for in situ staining of cellulose. The staining agent in conjugate of cellulase and fluorescein isothiocyanate (FITC). Application of this agent does not disturb intercellular or intracellular substances. The technique depends on the specific binding of the fluorescent labeled enzyme to its substrate. The stain has been tested on cell-free noncellulose polysaccharides similar to cellulose and does not stain them. The technique has been used to localize cellulose during the life cycle of Dictyostelium discoideum with results that correspond to previous work using other methods.
