Production of specific antibody against L-dopa and its ultrastructural localization of immunoreactivity in the house-shrew (Suncus murinus) lateral habenular nucleus.
An antiserum was raised against L-DOPA bound to bovine serum albumin, purified by affinity chromatography, and its specificities were verified by immunoblotting and enzyme-linked immunosorbent assays. The antiserum did not cross-react with dopamine (DA), tyrosine, tyramine, octopamine, norepinephrine or epinephrine. Immunocytochemical studies using the PAP method revealed that tyrosine hydroxylase- and L-DOPA positive but aromatic L-amino acid decarboxylase- and DA-negative neurons were present in the lateral habenular nucleus of the house-shrew (Suncus murinus) brain. Ultrastructurally L-DOPA immunoreactive products were localized in the cytoplasmic matrix and terminals with vesicles.
