Interpolated concentrations of native Ghrelin in human serum and plasma samples.

The concentrations of Ghrelin were measured in duplicates, interpolated from the Ghrelin standard curves and corrected for sample dilution. Undiluted samples are as follows : serum 50%, plasma (citrate) 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Ghrelin concentration was determined to be 25.69 pg/mL in neat serum and 31.66 pg/mL in neat plasma (citrate).

Human Ghrelin ELISA Kit (Ghrelin-28) (ab263887) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Ghrelin (Ghrelin-28) protein in cell culture media, cit plasma, hep plasma, and serum. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Ghrelin (Ghrelin-28) with 1.048 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

Our broad range of gold-standard reagents features highly specific recombinant antibodies and kits, validated across applications and species to ensure the precision and reproducibility your work requires. Drive your drug discovery efforts forward with our tailored solutions designed to meet the unique challenges of obesity research.

Ghrelin is a peptide hormone, it is a ligand of growth hormone secretagogue receptor type 1 (GHSR). It is involved in appetite stimulation and gastric acid secretion and induces adiposity. It is involved in growth regulation and induces the release of growth hormone from the pituitary. Ghrelin exists in two forms, Ghrelin-28 and one amino acid shorter Ghrelin-27. Both forms as well as Obestatin are generated by cleavage from common precursor protein, Appetite-Regulating Hormone coded by GHRL gene. Ghrelin-28 and Obestatin have non-overlapping amino acid sequences. O-octanoylation or O-decanoylation of Ghrelins is essential for Ghrelin activity.

Ghrelin also known as the "hunger hormone" or GH secretagogue is a peptide hormone with a mass of 28 amino acids. Ghrelin is mainly expressed in the stomach particularly in the enteroendocrine cells but it can also be found in small amounts in the lungs pancreas and hypothalamus. The hormone increases food intake and promotes fat storage by signaling the brain to stimulate hunger. Its secretion occurs in response to fasting and is suppressed by food intake reflecting its role in energy balance.

Biological function summary

Ghrelin influences a variety of physiological processes beyond hunger regulation. It plays a role in modulating the release of growth hormone by acting on the growth hormone secretagogue receptor (GHS-R). Ghrelin also affects gastric motility and acid secretion due to its expression in the gastrointestinal tract. Though not part of a larger complex its interaction with GHS-R strongly influences its biological functions. Ghrelin may also impact insulin secretion and sensitivity linking it to glucose metabolism processes.

Pathways

Ghrelin interacts with several critical biological networks. Ghrelin is involved in the neuroendocrine pathway that connects the gut to the brain and contributes significantly to energy homeostasis. Within this pathway it influences proteins like leptin which exerts opposite effects by suppressing hunger. Additionally ghrelin functions in the hedonic control of eating which relates to the rewarding aspects of food intake controlled by pathways involving dopamine.

Ghrelin holds relevance to obesity and cachexia a form of extreme weight loss often seen in chronic illness. Ghrelin promotes adiposity by stimulating appetite which can contribute to obesity. Conversely in cachexia the decrease in ghrelin activity is thought to exacerbate weight loss. Its role in energy balance associates ghrelin with the protein leptin which counterbalances its effects and connections to metabolic disorders. Understanding ghrelin’s functions and pathways provides insight into therapeutic strategies for these conditions.
