Abstract:Biogenic amines, with a primary amino group, were reacted with glutaraldehyde to form insoluble precipitates. These precipitates had distinctive ultrastructural features upon further reaction with osmic acid. When tested in vitro, they had biological activity and showed evidence that part of this biological activity was due to the large polymer of glutaraldehyde and amine. Experiments with isotope-labelled amines in the production of these precipitates showed that the precipitated polymers were not completely … Show more
