[Microspectrophotometric study of biogenic amines in ganglions of the central nervous system of Crepidula fornicata (Phil.)].

Abstract

The fluorescent products formed from biogenic amines treated with formaldehyde according to the method of Falck and Owman have been studied in the brain of Crepidula fornicata. The microspectrophotometric analysis of cellular indolamines shows excitation emission maxima at 385--525 nm (serotonine) and catecholamine at 410--475 nm upon HCl treatment catecholamine products show a shift of the excitation peak from 410 to 370 nm (dopamine).
