Product ID: 20073

*All Products sold by immunoStar are Tax Exempt.


The ImmunoStar Gastrin Releasing Peptide antiserum was quality control tested using standard immunohistochemical methods. The antiserum demonstrates strongly positive labeling of rat dorsal horn of spinal cord using indirect immunofluorescent and biotin/avidin-HRP techniques. Recommended primary dilution is 1/1,000-1/2,000 in PBS/0.3% Triton X-100 – Bn/Av-HRP Technique. Staining is completely eliminated by pretreatment of 1 mL of diluted antibody with 50 µg of bombesin.

Photo Description: IHC of at stomach staining for gastrin releasing peptide. The tissue was fixed with 4% formaldehyde in phosphate buffer, before being removed and prepared for frozen sectioning. Sections were incubated at RT in 10% goat serum in PBS, before standard IHC procedure. Primary antibody was incubated at 1:2000 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 and counterstained with hematoxylin

This is our first time using this antibody (Prod ID: 20073) from ImmmunoStar. It works beautifully in our immunohistochemical assays on mouse dorsal tissues. We used 1:2000 dilutions. It is one of the best ones among similar antibodies we have tested from other vendors. We would like to recommend this item to our colleagues.
