Kas·ten fluor·es·cent Schiff re·a·gents

(kas'tĕn),
fluorescent analogs of Schiff reagent that are fluorescent basic dyes lacking acidic side groups and containing one or more primary amine groups; used in cytochemical detection of DNA in Kasten fluorescent Feulgen stain, polysaccharides in Kasten fluorescent periodic acid-Schiff stain, and proteins in the ninhydrin-Schiff stain; such analogues include acriflavine, auramine O, and flavophosphine N.
