Calcofluor-white Calcofluor-white Calcofluor-white is a special fluorescent stain that binds strongly to structures containing cellulose and chitin. In plant cell biology research, it is used for the staining of cell walls of both algae and higher plants. It is also useful in medicine and animal biology for the identification of fungi in the tissue, (it binds to the chitin in the cell walls of the fungi). In research, calcofluor-white is also used to stain bud scars of yeast cells because the bud scars have a higher content of chitin, which stains them more than the rest of the cell membrane. Due
Fluorescent glucose biosensor assay between glucose and a labelled glucose polymer for the binding site of Concanavalin A. Over the years, using a combination of rational design and screening approaches, many possible combinations of fluorescent sensor for glucose have been studied with varying degrees of success: In most approaches, the glucose concentration is translated into a change in fluorescence either by using a pair or by using environment sensitive (solvatochromic) dyes in a variety of combinations, the fluorescent small molecule, protein or quantum dot have been used in conjunction with a glucose binding moiety either a boronic acid functionalized fluorophore or a protein,
