  • Function

    Liver-produced hormone that constitutes the main circulating regulator of iron absorption and distribution across tissues. Acts by promoting endocytosis and degradation of ferroportin, leading to the retention of iron in iron-exporting cells and decreased flow of iron into plasma. Controls the major flows of iron into plasma: absorption of dietary iron in the intestine, recycling of iron by macrophages, which phagocytose old erythrocytes and other cells, and mobilization of stored iron from hepatocytes (PubMed:22306005).
    Has strong antimicrobial activity against E.coli ML35P N.cinerea and weaker against S.epidermidis, S.aureus and group b streptococcus bacteria. Active against the fungus C.albicans. No activity against P.aeruginosa (PubMed:11113131, PubMed:11034317).
  • Tissue specificity

    Highest expression in liver and to a lesser extent in heart and brain. Low levels in lung, tonsils, salivary gland, trachea, prostate gland, adrenal gland and thyroid gland. Secreted into the urine.
  • Involvement in disease

    Hemochromatosis 2B
  • Sequence similarities

    Belongs to the hepcidin family.
  • Cellular localization

    Secreted.

Question

Product code: 31875
Lot number: GR76589-1

Inquiry: I'm working on the development of ELISA Hepcidin.
Antibodies anti-Hepcidin generated at Diaclone and an other one generated by a collaborator well recognize hepcidin purchased from a concurrent but do not recognize yours.
I tested it with a sandwich ELISA and with a direct ELISA, without success.

Please see above our experimental conditions:
- Direct ELISA : coating : Hepcidin 500ng/ml (100µl/well) in PBS O/N +4°C Wash blocking: 250µl/well BSA 5% 2H RT Wash primary antibody : 10µg/ml diluted 10 fold on 7 points (BSA1%) 1H RT Wash secondary antibody : goat anti-mouse IG1 HRP, 1H RT Wash Substrate: TMB 100µl/well 15' RT Stop with 100µl/well H2SO4 -Sandwich ELISA coating: capture antibody 10µg/ml(100µl/well) in PBS O/N +4°C wash blocking: 250µl/well BSA 5% 2H RT Wash Hepcidin standard : 1µg/ml diluted 2 fold on 7 points (BSA1%) 2H RT Wash biotinylated detection antibody : 1µg/ml (100µl/well) (BSA 20%) 1H RT Wash Streptavidin HRP : 100µl/well 30' RT wash Substrate: TMB 100µl/well 15' RT Stop with 100µl/well H2SO4 See in attachment data obtained.

Asked on Jun 19 2012

Answer

Merci de nous avoir contactés.

Je suis désolé que le produit ne fonctionne pas.

L'explication est très probablement la suivante: la longueur de ce peptide n'est que de 25 acides aminés (aa 60-84 de l'hépicine humaine). Ce peptide sert d'immunogène de l'anticorps ab75883.

J'ai parcouru la fiche technique qui, j'en suis désolé, contient une information qui porte à confusion , à savoir la longueur de la protéine (et non du peptide) qui est de 84 acides aminés.

J'ai demandé à ce que cette information soit reformulée ou supprimée de la fiche technique.

Nous n'avons pas à notre catalogue l'hépicine entière. Je veux bien néanmoins procéder à l'édition d'un avoir / remboursement en compensation de cette confusion.

Merci de me confirmer que cette résolution vous convient.

Asked on Feb 23 2012

Answer

Thank you for contacting us.

The peptide should already be in solution. Is that not the case? You should have 100ul. Be sure to centrifuge the tube to pulll down any solution trapped in the threads of the tube.

If you want to further dilute the stock solution, distilled water will be fine.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Answer

Thank you for contacting us.

The product ab31875 is a synthetic 25 amino acid peptide that is not, to our knowledge, active. This peptide has been used to produce the antibody ab75883, which is validated for use on mouse and human samples in WB, IHC-Fr, and ICC/IF. I hope this helps, please let me know if you have any other questions.

Question

We appreciated the advice we have obteined from Abcam, but I communicate that the use, in our experiments, of 12% gels with MES SDS buffer is equivalent to having done running the proteins at in a gel of approximately 18% polyacrylamide, so we are confident that the protein of our interest has not been lost.

Please let me know if you can send the the immunizing peptide for blocking experiments.

Answer

Thank you for your reply.

I am still concerned that the resolving conditions are not suitable for such a small protein. I will send on the peptide as an exception. However, I am not sure how it will be used for blocking if a band of the appropriate size is not detected.

Please confirm the order number and date of shipping so that I can send on the peptide. Looking forward to your reply.

Question

Thanks very much for your detailed response, that’s helpful. Just a couple of further questions/comments: when you state that the peptide sequence corresponds to aas 60-84, are you referring to ab31876 or ab31875 or both? There is evidence in the literature that pro-hepcidin is found in the blood as well as located intracellularly, and pre-pro-hepcidin can also be secreted from cells. I do think it might be helpful for customers to know that the ‘hepcidin-25’ antibodies are likely to recognise other forms of hepcidin (since it can be important to distinguish between active hepcidin and inactive precursors), and therefore it would be good to provide this information on the data sheet.  I hope to place an order for one of the hepcidin peptides and some anti-hepcidin antibodies soon. Best wishes,

Asked on Sep 16 2011

Answer

Thanks you for your email. Dr. Tanya is away this week so I am looking after her inbox. The peptide sequence for ab31876 corresponds to amino acid XXXX and peptide sequence for ab31875 corresponds to XXXX amino acids. The antibody cross reactivity always depends on the immunogen sequences, so customers will automatically know from the datasheet e.g. which part of the immunogen the antibody is specific to and in which part of the processed protein, the immunogen lies. This is very obvious information so we do not think we need to publish this information. However we are always happy to answer any inquiry we receive regarding there products. I hope this will be helpful. Should you any other please does not hesitate to contact us.

Question

Hi, I have a query about this product (hepcidin-25 peptide). I don't understand why this product is termed 'hepcidin-25' when it is actually full length pre-pro-hepcidin rather than the 25 amino acid active form of hepcidin. It's very misleading, can you explain what you mean by 'hepcidin-25' here? I'm also confused about the 'hepcidin-25' antibodies you have - are these specific to the 25 aa form or the 84 aa protein? Many thanks for your help,

Asked on Aug 30 2011

Answer

Thank you for your enquiry and your interest in our products. I have conducted a quick blast and the peptide sequence picks up both hepcidin and hepcidin 25. The peptide sequence corresponds to aas 60-84 of the full length protein. The antibody recognizes the processed hepcidin 25 (60-84 aa) which will be found at low concentrations in the blood (presumably) and it will also detect the full length pre-pro protein which would be found in the cell – hence easier to run on a Western blot. Therefore it would be very difficult to get an antibody specific for the processed protein. I hope this helps and if I can assist further, please do not hesitate to contact me.

Can you please tell me how this peptide was fabricated and purified?

Verified customer

Asked on Apr 07 2011

Answer

Thank you for contacting us. This peptide was synthesised on solid phase, using Fmoc-protected amino acids. Amino acid side-chains are protected. The full length peptide is cleaved from the resin and fully deprotected using 95% TFA and scavenger mix to remove protecting group by-products. The crude peptide is purified by reverse phase HPLC, using aqueous acetonitrile with 0.1% gradient. The peptide pool is then lyophilized, and is supplied in fully reduced form (ie no disulfide bridges), and TFA salt. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
