Bacterial Capsule Stain

Bacterial Capsule Stain

Intended Use

It is mainly used for staining to observe the presence or absence of a capsule structure on the cells.


Capsule is a characteristic mucous substance developed external to but contagious with the cell wall during bacteria's life cycle. The capsule can protect bacteria from phagocytosis and subsequent digestion by their host, thus increasing their infectivity. Capsules can only be stained with certain special stains. Identification of capsules is very important for bacteria grouping and differentiation.
