Abstract
A highly sensitive and specific monoclonal antibody against the enzyme dopamine beta-hydroxylase (DBH) from rat was produced and coded DBH 41. The generated hybridoma secreted immunoglobulins of mouse IgG1 subtype, as determined by radial immunodiffusion. This antibody, characterized by immunoblotting against a crude rat DBH preparation, was found to specifically recognize two bands of molecular weight 70 and 75 kDa corresponding to the soluble and membrane bound forms of the enzyme, respectively. With regard to species specificity, the anti-DBH antibody recognizes only the rat DBH molecule as it exhibits no cross-reactivity with either mouse, human, rabbit, guinea pig, cat or bovine DBH. Comparative immunocytochemical localization of DBH and TOH immunoreactivity was performed in different brain regions and we found that the DBH 41 antibody specifically stained DBH-containing neurons and fibers in the rat central nervous system (CNS). The high sensitivity of the DBH 41 antibody permitted us to detect immunologically the presence of the enzyme even in areas where only scattered DBH-containing fibers were present.
