Description The ImmunoStar Oxytocin antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat hypothalamus using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilution is 1/4,000 – 1/8,000 in PBS/0.3% Triton X-100 – Bn/Av-HRP. Staining is completely eliminated by pretreatment of 1 mL of the diluted antibody with 5 µg of Oxytocin. Pretreatment of 1 mL of the diluted antibody with as much as 100 µg of vasopressin does not diminish staining. Photo Description: IHC image of neurons staining for oxytocin in the rat hypothalamus (above) and higher magnification of the rat hypothalamus with nickel preparation (below). The tissue was fixed with 4% formaldehyde 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 1:5000 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.
