Both acinar cells and pleomorphic adenoma cells possess a cell surface protease, guanidinobenzoatase (GB) which can be located with a fluorescent probe for the active centre of this enzyme. We have developed a rapid, cheap, fluorescent technique for the differential location of pleomorphic adenoma cells and acinar cells in frozen sections of salivary glands. The fluorescence of other cells (which also possess GB) is selectively quenched, such that only the acinar and pleomorphic adenoma cells are visualised by fluorescent microscopy.

UI	MeSH Term	Description	Entries
D008949	Adenoma, Pleomorphic	A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity. It is most often seen in women in the fifth decade. Histologically, the tumor presents a variety of cells: cuboidal, columnar, and squamous cells, showing all forms of epithelial growth.

D010450	Endopeptidases	A subclass of PEPTIDE HYDROLASES that catalyze the internal cleavage of PEPTIDES or PROTEINS.	Endopeptidase,Peptide Peptidohydrolases
D002265	Carboxylic Ester Hydrolases	Enzymes which catalyze the hydrolysis of carboxylic acid esters with the formation of an alcohol and a carboxylic acid anion.	Carboxylesterases,Ester Hydrolases, Carboxylic,Hydrolases, Carboxylic Ester
D005453	Fluorescence	The property of emitting radiation while being irradiated. The radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible radiation and emit visible light. X-ray fluorescence is used in diagnosis.
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000585	Aminacrine	A highly fluorescent anti-infective dye used clinically as a topical antiseptic and experimentally as a mutagen, due to its interaction with DNA. It is also used as an intracellular pH indicator.	9-Aminoacridine,Acridinamine,Aminacrine Hydrochloride,Aminoacridine,Aminoacridine Hydrochloride,Aminopt,Mykocert,9 Aminoacridine,Hydrochloride, Aminacrine,Hydrochloride, Aminoacridine
