| abstract |
A method for the fluorometric or electrochemical assaying of low levels of primary amines and more particularly, biogenic and endogenous amines such as catechol amines, amino acids, and peptides, by reacting a substituted or unsubstituted naphthalene-2-3-dicarboxyaldehyde with the non-fluorescing primary amine of interest in the presence of a cyanide ion under mildly alkaline conditions thereby to form an entity which is amenable to both fluorescent and electrochemical detection. |
