Kasten fluorescent Schiff reagents


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.
