Differential Staining of Bacteria: Capsule Stain
Current Protocols in Microbiology, 2009AbstractBacterial capsules are composed of high‐molecular‐weight polysaccharides and/or polypeptides, and are associated with virulence and biofilm formation. Unfortunately, capsules do not stain well with crystal violet, methylene blue, or other simple stains. This unit describes two methods of capsule staining.

Differential Staining of Bacteria: Endospore Stain
Current Protocols in Microbiology, 2009AbstractEndospore production is a very important characteristic of some bacteria, allowing them to resist adverse environmental conditions such as desiccation, chemical exposure, extreme heat, radiation, etc. The identification of endospores is also very important for the clinical microbiologist who is analyzing a patient's body fluid or tissue—there ...

Differential Staining of Bacteria: Gram Stain
Current Protocols in Microbiology, 2009AbstractIn 1884, Hans Christian Gram, a Danish doctor, developed a differential staining technique that is still the cornerstone of bacterial identification and taxonomic division. This multistep, sequential staining protocol separates bacteria into four groups based on cell morphology and cell wall structure: Gram‐positive cocci, Gram‐negative cocci ...

Coffee stain on textiles. Mechanisms of staining and stain removal
Journal of the American Oil Chemists' Society, 1995AbstractCoffee stains on textiles are mainly caused by the water‐soluble and acidic colored substances in coffee. The acidic nature of coffee stain has been shown by ultraviolet and visible spectroscopy of coffee as a function of pH; ion‐pair formation with a cationic surfactant and titration with Hyamine 1622 and a surfactant‐specific electrode; and ...

Historically, the diagnosis and classification of acute leukemia involved morphologic review of blasts in the peripheral blood and bone marrow smears and cytochemical staining. Cytochemical stains, which are enzymatic colorimetric reactions that occur in the cells of interest, were necessary to assign and confirm myeloid and lymphoid lineage.

Stain Technology, 1948
A review of the various methods of staining and mounting radulae is given. Normally the radula should be extracted with 0.5 to 1% sodium hydroxide solution, and the associated tissues removed before staining. Two staining methods are recommended for facilitating the interpretation of radulae.
