  • General notes

    Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.

    Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.

    We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.

    In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.

    We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.

    Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.

Properties

Target

  • Function

    Ghrelin is the ligand for growth hormone secretagogue receptor type 1 (GHSR). Induces the release of growth hormone from the pituitary. 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.

  • Tissue specificity

    Highest level in stomach. All forms are found in serum as well. Other tissues compensate for the loss of ghrelin synthesis in the stomach following gastrectomy.

  • Sequence similarities

    Belongs to the motilin family.

  • Post-translational
    modifications

    O-octanoylation or O-decanoylation is essential for ghrelin activity. The O-decanoylated forms Ghrelin-27-C10 and Ghrelin-28-C10 differ in the length of the carbon backbone of the carboxylic acid bound to Ser-26. A small fraction of ghrelin, ghrelin-28-C10:1, may be modified with a singly unsaturated carboxylic acid.
    Amidation of Leu-98 is essential for obestatin activity.

Question

The antibody ab48285 at 4 ug/ml did not work well in our system. In fact, by using this much antibody, we can only make 25 ml of 4 ug/ml. In each RIA tube, we have the incubation volume of 0.5 ml. Thus, with 100 ug of ab48285 we can only run 50 tubes. If we would run ab48285 at 8 ug/ml, then we can only run 25 tubes. As you can see that this would not be economical. When we ordered this antibody, we were hoping that it would work out at 2 ug/ml; we tested both 2 ug/ml and 4 ug/ml, they yielded 5% and 10 % specific binding, respectively. With this kind of binding result, I do not expect 8ug/ml of ab 48285 will give us adequate binding for RIA.

I hope you will give us credit at this time.

We had good experience with your products, and will not hesitate to try more of your products in the future.

Question

I was testing your product rabbit polyclonal to ghrelin (ab48285) in our RIA system, and it failed. Following your instruction, I used 4 ug/ml but the specific binding of 125I-ghrelin was only 10%, whereas the antibody from another company showed 30% specific binding. I understand that you would refund the cost if the customer is not satisfied with your product.

Answer

Thank you for contacting Abcam regarding ab48285.


I am sorry that you have been experiencing difficulties with this antibody in your RIA experiments. I understand that you have tested a concentration of 4ug/ml - have you tested any others? We recommend up to 8ug/ml. Some further optimization may be required for best results with this antibody.


If increasing the amount of antibody used does not improve your results with this antibody, I am happy to offer a replacement or credit. Please do not hesitate to contact me if you have any additional questions.

Question

I am interested in using your product ab48285 to set up an RIA of ghrelin. Do you have any information regarding the use of this product for RIA? For example, I would like to know how much I should dilute this antibody to do RIA? What is the lowest concentration I can detect using this antibody?

Answer

Thank you for contacting us.

The supplying lab sent us the following information:

The antibody isrecommended from 2-8 ug/ml for RIA purpose. The efficiency of labeling of their tracer is another factor to determine the concentration use for their RIA assay.The optimal condition would need to be determined by the enduser.

I am sorry that we did not receive more detailed information than this.
Please do not hesitate to contact us if you need any more advice or information.
