Immunocytochemical demonstration of taurine.

Amino acid immunocytochemistry represents a new and powerful tool in neuroscience. Antisera are now available to a large number of amino acids, including those that are thought to serve a transmitter role. The antiserum described here against conjugated taurine seems to be of good specificity and can be used to demonstrate taurine in the CNS as well as in other organs; in normal tissue and in experimental and pathological conditions.
