  • Epitope
    Residues 21-31

  • General notes

    Though we have found ab13420 does not react with mouse sample in our lab, there is a report from a reviewer that got positive result with mouse sample in IHC-Fr. However, this information needs to be confirmed further.

    Although this antibody does work in IHC-P, we have found that ab13418 typically gives a more robust signal. Therefore, if you plan on using this antibody in IHC-P, we recommend ab13418 as an alternative option.



Our Abpromise guarantee covers the use of ab13420 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 1 - 10 µg/ml. Predicted molecular weight: 12 kDa.

Use under reducing or non-reducing conditions.

IHC-Fr Use a concentration of 1 - 10 µg/ml.
IHC-P Use a concentration of 10 µg/ml. Enzymatic retrieval with Proteinase K is recommended.
Sandwich ELISA Use a concentration of 1 - 10 µg/ml.

For use in sandwich ELISA with ab13421

ICC/IF Use at an assay dependent concentration. PubMed: 21396708


  • Function
    Constitutes 1-2% of the total bone protein. It binds strongly to apatite and calcium.
  • Sequence similarities
    Belongs to the osteocalcin/matrix Gla protein family.
    Contains 1 Gla (gamma-carboxy-glutamate) domain.
  • Post-translational
    Gamma-carboxyglutamate residues are formed by vitamin K dependent carboxylation. These residues are essential for the binding of calcium.
  • Cellular localization

Thank you very much for contacting us with your enquiry.

The AMELX protein ab139212 can be diluted in any buffer. However, all of our products are intended for research use only and are not recommended for in vitro studies. This protein contains DTT, glycerol, and Tris HCL in its buffer, and it is not a sterile product, so we do not suggest it for use in a live animal study.

Ab13420 and ab90395 are mouse monoclonal antibodies, so they can be detected with a detection kit like ab94743-


I hope that this information will be useful, but please let me know if you have further questions or need anything else, and I'll be happy to help.

Vielen Dank für Ihre Anfrage.

Die Lieferung über das Wochenende erfolgt bei uns regelmaessig, ist also kein Grund zur Beunruhigung, da wir erstens den Antikörper mit Kuhlakkus versenden, zweitens FedEx die Produkte im Kühlhaus lagert und drittens Antikörper sehr stabile Proteine sind. So versenden wir unsere Produkte ja auch nach Ost-Asien und Australien, und da sind die schon mal locker eine Woche unterwegs.

Wir haben interne Versuche zur Aktivität unter verschieden Lagerbedingungen durchgeführt, und wir festgestellt, dass die meisten Antikörper sogar bei einer Lagerung für drei Monate bei Raumtemperatur ihre Aktivität nicht verlieren!

Wir testen äusserst selten Antikörper in anderen Applikationen als IHC-P oder IHC-F für die Immunohistochemie. Daher kann ich Ihnen leider nicht garantieren, ob unsere Antikörper mit dem technovit 9100neu Einbettugssystem funktionieren.

Hinsichtlich der zwei Antikörper kann ich Ihnen auf den ersten Blick sagen, dass der eine Antikörper aufgereinigt wurde (ab75043), und der andere nicht (ab75078). Desweiteren hat der ab75043 eine recht niedrige Affinität, da er in sehr hohen Konzentrationen eingesetzt werden muss.

Eine Positivkontrolle versenden wir leider nicht mit unseren Produkten. Und ja, die meistens unserer In-Haus Antikörper werden tatsächlich mit jedem neuen Lot aufs neue getestet, so dass unsere Datenblätter immer aktuell sind.

Ich hoffe, dies hilft Ihnen weiter. Bitte zögern Sie nicht, sich wieder bei uns zu melden, falls Sie weitere Fragen haben.

Thank you very much for your email.

I had sent a reply to this on Wednesday, but it seems that it did not get to your inbox. Could you please let me know once you receive this message? My previous message is below:

"Thank you very much for contacting us with your question.

The osteocalcin antibody ab13420 is provided at a concentration of 2 mg/mL, and we recommend using the antibody at 10 ug/mL in IHC-P. So, the antibody will need to be diluted 1:200 before use.

For example, if you need to use a total of 400 uL of antibody solution, you would add 2 uL of the provided antibody solution into 398 uL of diluent such as TBST.

I hope that this information will be useful, but if you have further questions or if there is anything else that we can do for you, please let me know and I'll be happy to help."
