LHRH (Luteinizing Hormone Releasing Hormone) / GnRH Antibody


Product ID: 20075

*All Products sold by immunoStar are Tax Exempt.


The antibody produces a strong postive labeling of LHRH / GnRH at dilution of 1/2,000 – 1,4,000 using biotin-streptavidin/HRP in rat hypothalamus (median eminence). Optimal dilution will vary depending upon fixation, labeling technique and/or detection system; therefore, a dilution series is recommended.

The above image is of LHRH (GnRH) terminals in rat median eminence, ryostat sections, ABC / DAB detection.

Staining is completely eliminated by pretreatment of the diluted antibody with 5 µg of LHRH per mL of diluted antiserum.

Photo Description: IHC image of staining for LNRH/GnRH in the rat median eminence. 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 1:4000 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.

Highly recommend — very specific staining with no background

I use the LHRH Antibody for immunohistochemistry on mouse embryonic tissue. I use cryostat sections of PFA fixed mouse heads, included in OCT.

I cut 10-20 microns sections, dry them and the process them as following: Protocol: 1hr blocking (PBS/0.1% triton plus 10% NGS), incubate overnight with LHRH antibody diluted in PBS/0.1% triton, 1:400. Then washes and secondary antibody fluorescent. When used with secondary biotinylated antibody, I use LHRH antibody less diluted (1:4000).

My student is also using the LHRH antibody on paraffin sections, with the same results (and also in conjunction with Tyramide amplification kit).

Staining is very specific. Stronger on adult tissue because more GnRH expressed by the neurons producing it. There is no background. Fixation sensitive; long fixations are not recommended. I highly recommend this antibody.
