Currently the Biological Stain Commission (BSC) offers certification for stains, which are listed in the following table (based on information in Conn’s Biological Stains, 10th edition, 2002 and publications in the Commission’s journal, most notably a detailed account of the testing methods and requirements for certification by Penney DP, Powers JM, Frank M, Willis C, Churukian C (2002) Analysis and testing of biological stains— The Biological Stain Commission Procedures. Biotech. Histochem. 77: 237-275. Papers in more recent issues of Biotechnic & Histochemistry contain details of a few stains added since 2002 and revised criteria for certification of some dyes. For summaries of recent changes, keep an eye on the What’s New feature of the BSC’s web site.

The BSC does not certify staining solutions. Certified stains are powders. They include dyes (most items) and a few other compounds (fluorescein isothiocyanate, protargol S, resazurin) that are used to improve visibility, mainly in the fields of human pathology, hematology and bacteriology, but also in microbial, animal and plant histology. Many dye powders contain more than one colored component. This can affect performance. For example, a certified basic fuchsine that is OK for staining acid-fast bacteria and making Schiff’s reagent might not work in the aldehyde-fuchsine method for staining insulin in the beta-cells of pancreatic islets. Beta-cell staining requires pararosaniline, one of the 4 components of basic fuchsine. (Pararosaniline is also sold as a single dye; it can be used in all applications requiring basic fuchsine.)
