Vasopressin Antibody


Product ID: 20069

*All Products sold by immunoStar are Tax Exempt.


The antibody has a proven strong biotin-streptavidin/HRP staining at a 1/2000 – 1/4000 dilution in rat hypothalamus.

Staining is completely eliminated by pretreatment of the diluted antibody with 10 µg/mL of arginine vasopressin. Pre-adsorption with as much as 100 µg/mL of oxytocin had no effect on immunolabeling.

Photo Description: IHC image of rat hypothalamus staining for vasopressin. 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.

Great antibody

This antibody is the best! I use it for visualizing vasopressin within the rat brain. 1:10,000 dilution results in beautiful staining of the magnocellular regions of the PVN and SON, as well as some staining in the BST and amygdala. My protocol is:

Day 1

_ _ _ Wash 3×5 min TBS

____ 0.1% sodium borohydride in TBS 15 min

_ _ _ Wash 3×5 min TBS

____ 20% normal serum and 3% H202 in TBS 1 hr

____ Primary antibody 1:10K with 2% normal serum in TBS -Triton over 3 nights @ 4º

Send good thoughts over the next 3 days

Day 2

_ _ _ Wash 3×5 min TBS- Triton

____ Secondary antibody 1:500 in TBS-Triton w/ 0.5% gelatin 90 min

____ Make ABC during last 20 min of 2o (25 ul each of A & B per 10 ml TBS)

_ _ _ Wash 1×5 min TBS- Triton, 2×5 min TBS

____ ABC 60 min

_ _ _ Wash 3×5 min TBS-Triton

____ Visualize with Vector SG (6 drops of each reagent per 10 ml TBS-T) + 0.5% gelatin

_ _ _ Wash 3×5 min TBS

Excellent for IHC

This is a high-quality antibody that we have found to consistently produce beautiful, specific staining. We used a 1:1,000 concentration in cryosectioned mouse brain slices following blocking with 10% serum. Labeled cell bodies and fibers were clearly discernable at 20x magnification in the hypothalamus. Highly recommended.

Beautiful cells

We have used your Vasopressin antibody (Product ID: 20069) in many of our studies and have found in to be a very specific and clear antibody. The staining is great and the cells are beautiful.

We use a total 1:5000 concentration. It is mixed with 10% serum, 10% biotin diluted in 80% PBS-T and incubated for 48-72 hours at 4 degrees C. We used brain tissue from Thamnophis sirtalis (Red-sided garter snake).
