Interpolated concentrations of native Obestatin in human plasma (EDTA) samples.

The concentrations of Obestatin were measured in duplicates, interpolated from the Obestatin standard curves and corrected for sample dilution. Undiluted samples are as follows : plasma (EDTA) 50%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2). The mean Obestatin concentration was determined to be 289 pg/mL in plasma (EDTA).

Product details

Human Obestatin ELISA Kit (ab264628) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Obestatin protein in edta plasma. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human Obestatin with 8 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.

Obestatin, is generated from the proteolytic cleavage of preproghrelin; its sequence corresponds to amino acids 76-98 of Appetite-regulating hormone [Precursor](Q9QYH7). This peptide has contrasting actions to Ghrelin (a different product of proteolytic cleavage of preproghrelin) in that it inhibits food intake and gastrointestinal motility but does not modify in vitro GH release from pituitary cells.

Supplementary information

Obestatin also known as the obestatin hormone is a 23-amino acid peptide with a mass of approximately 2.5 kDa. Researchers discovered it as a cleavage product from the Ghrelin preprohormone. Obestatin is mainly expressed in the stomach and small intestine but one can also find it in other tissues such as the pancreas and adipose tissue. This peptide acts mechanically by binding to its receptor GPR39 although the binding affinity and downstream effects remain subjects of investigation.
Biological function summary

This peptide hormone interacts with several bodily processes mostly related to gastrointestinal functions and energy homeostasis. It does not form part of a larger protein complex but acts independently. Studies suggest it could play roles in reducing food intake and slowing down gastric emptying potentially contrasting the action of Ghrelin which stimulates hunger. Understanding its precise biological role remains complex with ongoing research needed to clarify its function fully.

Pathways

Several metabolic circuits include obestatin within their framework. It engages in pathways associated with energy balance and gut motility. In relation to the ghrelin axis specialists evaluate its potential modulatory effects given its origin from the same precursor. So far research indicates possible interplay with pathways influencing insulin release although the mechanistic details are not yet fully understood.

Preliminary research indicates obestatin might have connections to obesity and metabolic syndrome. Some scholars propose a potential protective effect against weight gain but findings often vary. Obestatin's relationship with the aforementioned diseases might involve its interaction with ghrelin highlighting a complex regulatory network that warrants further investigation. These insights could lead to novel therapeutic avenues for tackling metabolic disorders.

Ghrelin-27. Ghrelin is the ligand for growth hormone secretagogue receptor type 1 (GHSR) (PubMed : 10604470). Induces the release of growth hormone from the pituitary (PubMed : 10604470). Has an appetite-stimulating effect, induces adiposity and stimulates gastric acid secretion. Involved in growth regulation.. Ghrelin-28. Ghrelin is the ligand for growth hormone secretagogue receptor type 1 (GHSR) (PubMed : 10604470). Induces the release of growth hormone from the pituitary (PubMed : 10604470). Has an appetite-stimulating effect, induces adiposity and stimulates gastric acid secretion. Involved in growth regulation.. Obestatin. May be the ligand for GPR39. May have an appetite-reducing effect resulting in decreased food intake. May reduce gastric emptying activity and jejunal motility (By similarity).
