Histochemical demonstration of tryptamine. Properties of the formaldehyde‐induced fluorophores of tryptamine and related indole compounds in models

Abstract

A sensitive histochemical fluorescence procedure for the demonstration of tryptamine by a formaldehyde condensation reaction has been devised. This gives a 13–18 fold increase in the fluorescence yield of tryptamine compared with the conventional Falck‐Hillarp method …
