Abstract:
Nearly 89 years ago, the Society of American Bacteriologists appointed Dr. Harold Conn to form a committee to standardize the stains and dyes used in biological and medical research and diagnosis. Dr. Conn's efforts led to formation of the Committee on the Standardization of Biological Stains, later incorporated as the Biological Stain Commission. This article traces some of the events and factors that shaped the course of the Biological Stain Commission into its current form and functions. Its principal function is to ensure that the biological and medical communities have access to high quality, dependable and consistent biological dyes and stains.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
