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
Polymer blend more than one kind of polymer. A new polymers modification process, based on a simple mechanical mixture of two polymers first appeared when Thomas Hancock got one mixture of natural rubber with gutta-percha. This process generated a new polymer class called "polymer blends". Polymer blends can be broadly divided into three categories: The use of the term polymer alloy for a polymer blend is discouraged, as the former term includes multiphase copolymers but excludes incompatible polymer blends. Examples of miscible polymer blends: Polymer blends can be used as thermoplastic elastomer Polymer blend A polymer blend, or polymer mixture, is a
