The Rat Ghrelin ELISA Kit is specifically designed for the accurate and sensitive detection of ghrelin levels in rat serum, plasma, and tissue culture supernatants. Ghrelin is a peptide hormone that plays a key role in regulating appetite, energy metabolism, and growth hormone secretion. This ELISA kit offers high sensitivity and specificity, ensuring precise and reproducible results for a wide range of research applications. Ghrelin has been implicated in various physiological processes, including food intake, glucose homeostasis, and gastrointestinal motility, making it a valuable biomarker for studying metabolic disorders, obesity, and other related conditions.
With this kit, researchers can easily measure ghrelin levels in rat samples, helping to advance our understanding of ghrelin's role in health and disease and potentially leading to the development of innovative therapies targeting ghrelin signaling pathways.

Step
Procedure
1
Reagent & Plate Preparation: Equilibrate reagents and TMB substrate to room temperature. Set standard, test sample and control (zero) wells on the pre-coated plate and record their positions.
2
Primary Incubation: Prepare standards, samples, blanks and load into designated wells. Incubate plate at 37°C for 90 minutes to allow antigen binding.
3
Detection Antibody Binding: Add biotin-labeled detection antibody and incubate at 37°C for 60 minutes.
4
HRP-Streptavidin Binding: Add HRP-Streptavidin (SABC) and incubate at 37°C for 30 minutes.
5
Color Development: Add TMB substrate and incubate in the dark for 10–20 minutes.
6
Stop Reaction & Reading: Add stop solution and measure absorbance at 450 nm immediately.
Sample Type
Protocol
Serum
Allow blood to clot, centrifuge at 1000 × g for 20 minutes, collect supernatant supernatant and store appropriately.
Plasma
Collect using anticoagulant tubes, centrifuge at 1000 × g for 15 minutes at 2–8°C and collect plasma.
Tissue Homogenate
Homogenize tissue in PBS with protease inhibitors, centrifuge and collect supernatant.
Cell Culture Supernatant
Centrifuge at 2500 rpm for 5 minutes and collect clarified supernatant.
Cell Lysate
Lyse cells using lysis buffer with protease inhibitors, centrifuge and collect protein supernatant.
