Anti-dopamine beta-hydroxylase-saporin (anti-DBH-SAP, Cat. #IT-03) is a highly specific noradrenergic lesioning agent. It specifically targets rat cells that express dopamine beta-hydroxylase and is also reported to react with mouse protein.1 This vesicular enzyme is exposed to the exterior milieu upon release of noradrenaline and thus allows these cells to be targeted with saporin.
The specificity of Anti-DBH-SAP correlates well with uptake of the antibody when injected intraventricularly. After systemic administration, animals have a massive reduction in plasma norepinephrine levels, indicating efficient targeting and sympathectomy. Unlike other lesioning methods, this molecular lesioning agent assures definitive ablation of the target neurons.
Permanent and selective removal of cerebral noradrenergic innervations provides an important animal model for the study of drug effects, behavior, plasticity of other systems in response to loss, and primary autonomic failure.
