title: Simple butyrate esterase stain for monocytes.
abstract: The esterases used to identify monocytes are best demonstrated using alpha-naphthyl butyrate as substrate. However, the reagents commonly used for this stain are time-consuming to prepare and are unstable. This report describes a quick, easy, and reproducible staining method using stable reagents which are readily available commercially but which may also be prepared in the laboratory.
