The Sheep GnRH (Gonadotropin-Releasing Hormone) ELISA Kit is specifically designed for the accurate measurement of GnRH levels in sheep serum, plasma, and cell culture supernatants. With high sensitivity and specificity, this kit delivers reliable and reproducible results, making it perfect for a variety of research applications. Gonadotropin-Releasing Hormone (GnRH) is a key hormone involved in the regulation of reproductive functions in animals. It stimulates the release of gonadotropins, which then control the production and release of sex hormones like estrogen and testosterone.
Understanding GnRH levels is essential for studying reproductive health and fertility in sheep. This ELISA kit provides researchers with a valuable tool for studying the reproductive system in sheep, aiding in the development of new strategies for improving breeding and reproduction outcomes. With its ease of use and precise results, the Sheep GnRH ELISA Kit is a must-have for any researcher working in the field of reproductive biology.

Step
Procedure
1
Reagent & Plate Preparation: Equilibrate TMB substrate for 30 minutes at room temperature. Prepare standards, samples (minimum 1:2 dilution), blanks, assign wells, and pre-wash the plate twice.
2
Sample & Biotin-Antibody Binding: Add 50 µL standard or sample followed by 50 µL biotin-labeled antibody to each well. Mix gently and incubate at 37°C for 45 minutes.
3
Washing: Wash the plate 5 times with wash buffer, allowing 1 minute soak time per wash.
4
Color Development: Add TMB substrate and incubate in the dark at 37°C for 10-20 minutes until color develops.
5
Stop Reaction: Add stop solution to terminate the reaction. The color changes from blue to yellow immediately.
6
Reading: Measure absorbance at 450 nm using a microplate reader.
