Somatostatin Antibody


Product ID: 20067

*All Products sold by immunoStar are Tax Exempt.


The antibody has a proven strong Biotin-Streptavidin/HRP staining at a 1/1000-1/2000 dilution in rat hypothalamus (median eminence). The specificity of the antiserum was examined by soluble pre-adsorption with the peptides in question at a final concentration of 106M.

Somatostatin immunolabeling was completely abolished by pre-adsorption with somatostatin, somatostatin 25, and somatostatin 28. Pre-adsorption with the following peptides resulted in no reduction of immunostaining: substance P, amylin, glucagon, insulin, neuropeptide Y, and VIP.

Photo Description: IHC image of the median eminence staining for somatostatin (above). 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. Florescent secondary (below).

Strong, Cell-Specific Labeling

Tissue: Maccaca fasciscularis, perfused with saline and 4% paraformaldehyde, dehydrated through increase sucrose gradients, sectioned at 40 um.

Method: Immunocytochemistry on free floating sections. Incubated with ImmunoStar’s primary antibody at a concentration of 1:1000 for 4 days in 10% normal goat serum (in 0.1M PO4 buffer with .3% Triton X-100). Rinsed, then incubated with Vector Lab’s biotinylated goat anti-rabbit secondary antibody (#BA-1000) for 40 minutes at room temperature in the same 10% normal goat serum solution. Rinsed, then incubated with Vector’s standard peroxidase kit (#PK-4000) for 60 minutes at room temperature in 0.1M PO4 buffer with 0.3% Triton X-100. Rinsed, then developed using the instructions for the kit.

Results: Strong, cell-specific labeling. Crisp, punctuate cell bodies. Low background signal. Extremely helpful for delineating the boundaries of the lateral core of the bed nucleus of the stria terminalis (BNST).
