Demonstration of catecholamines in peripheral adrenergic nerves in stretch preparations with fluorescence induced by aqueous solution of glyoxylic acid.
Fluorescence induced by aqueous solution of glyoxylic acid and formaldehyde-induced fluorescence of catecholamines were compared for the demonstration of peripheral adrenergic nerves in stretch preparations. Glyoxylic acid was better than formaldehyde for the demonstration of the adrenergic nerves. On the other hand, the formaldehyde was better than glyoxylic acid for the demonstration of biogenic amines in cell bodies.
