The antibody produces moderate labeling of raphe neurons in normal rat. In rats whose serotonergic system has been activated, staining intensity is increased to a maximum label. Recommended dilution of the antiserum is 1/4000-1/8000 for biotin-streptavidin/HRP technique.
The specificity of the antiserum was evaluated using a model system of gelatin-indole plugs by a method similar to published procedures (Schipper and Tilders, 1983). Results showed that the 5-HIAA antibody dose dependently stained 5-HIAA but did not stain any concentration of 5-HT or 5-HTP. The antiserum was also tested by pre-adsorption at 25 µg/mL with various BSA conjugates. While pre-adsorption with 5-HIAA conjugate completely eliminates immunolabeling, pre-adsorption with conjugates of 5-HT,5-HTP and dopamine had no effect on staining intensity or distribution of stain.
Photo Description: IHC image of neurons staining for 5-H1AA in the raphe nucleus of the rat brainstem. The tissue was fixed with 4% formaldehyde in phosphate buffer, before being removed and prepared for vibratome sectioning. Floating sections were incubated at RT in 10% goat serum in PBS, before standard IHC procedure. Primary antibody was incubated at 1:5000 for 48 hours, goat anti-rabbit secondary was subsequently added for 1 hour after washing with PBS. Light microscopy staining was achieved with standard biotin-streptavidin/HRP procedure and DAB chromogen.
