ab6336 in rat brain tissue fixed with 4% paraformaldehyde. The staining is appropriate, lighting up cell bodies, dendrites and terminals of known 5-HT containing neurones. These pictures are from the review provided by Jim Deuchars.

IHC image of Serotonin staining in mouse brain (coronal) formalin fixed paraffin embedded tissue section, performed on a Leica Bond^TM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab6336, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Paraformaldehyde-fixed rabbit spinal cord tissue stained for Serotonin using ab6336 at 1/200 dilution in immunohistochemical analysis. Power Block™ Universal Blocking Reagen t(Biogenex) was used as ablocking agent for 10 minute(s) at a concentration of 10% at 37°C. Biotin-SP-conjugated Goat Anti-Rat IgG was used as the secondary antibody at 1/500 dilution.
