The ImmunoStar 5-HT2C receptor antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat choroid plexus and hippocampus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilutions are 1/500 – 1/1000 in PBS – Bn/Av-HRP technique. Intensification methods such as nickel will approximately double the dilution factor as recommended.
The antibody was characterized by immunohistochemistry and Western blot. Western blotting revealed a single band of approximately 70 kD. Due to the difficulty with receptor antibodies, western blot applications are not warranted and are included as specificity information only.
Preincubation of the antibody with an excess of the synthetic peptide blocked staining. Immunohistochemical staining of rat brain correlates well with Northern analysis, in situ hybridization and receptor autoradiography. BlastP database sequence homology searches confirmed that this sequence is unique to rat, mouse and human 5-HT2C receptors.
Photo Description: Gray scale IHC image of coronal rat brain section staining for the 5-HT2C receptor (above) and high magnification image of receptor expression in the cortex of the rat brain (below). The tissue was fixed with 4% formaldehyde/0.05% glutaraldehyde in 0.1 M 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 1:1000 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.
