  • Function

    Triggers NCR3-dependent natural killer cell activation.
  • Tissue specificity

    Not detected in any normal tissue tested. Expressed at the surface of several tumor cell lines including T and B lymphomas, myeloid leukemias, melanomas, carcinomas and large T SV40 antigen-transformed cells (at protein level).
  • Sequence similarities

    Contains 1 Ig-like C1-type (immunoglobulin-like) domain.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Domain

    The C-terminal part is similar to retroviral Gag protein. This putative protein seems to be the result of a fusion between an Ig-like domain-containing protein and a ERV.

  • Anti-B7-H6 antibody (ab121794) + HL-60 cell lysate

    Predicted band size: 51 kDa

  • ab121794, at 1/50 dilution, staining B7-H6 in paraffin-embedded Human gallbladder tissue, by Immunohistochemistry.
  • ab121794 at 1/50 dilution staining a cell-clot mixture of JVM (B7-H6 neg) and Hela (B7-H6 pos) (5:1) cells by IHC-P. The cell matrix section was subjected to heat-mediated antigen retrieval using 10 mM Citrate Buffer pH6 before being blocked with 10% horse serum for 30 minutes at 23°C and then being incubated with ab121794 (1/50 dilution) for 16 hours at 4°C. The secondary used was a Biotin conjugated goat anti-rabbit polyclonal (1/200 dilution).

Thank you for contacting us.

I have discussion with our IT department - unfortunately they do not save the previous versions of datasheets when updating them. The online datasheets along with pdf's gets updated every 15-20 days which is necessary for consistency between the two. I am sorry we will unable to provide you the version older than 5th Nov 2012.

The pdf's gets updated irrespective of changes the datasheet team makes for example the new version will be exactly the same if no information was added or deleted.

Please note that we do track the data we change on the datasheet so if there is any difference between the old and new, we do know what has been changed. For ab121794 WB application was deleted as we discussed on phone.

As far as we are aware, this antibody has also not been added into any of the news letter.

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

Thank you for your message which has been forwarded to me as my colleague Claudia is not in the office.

I apologise for the delay in resonding. We are still waiting for further information regarding your offer of testing from our business developement department.

Regarding free sampoes,I am sorry to confirm that because we carry over 90,000 products, it isn't feasible for us to keep small sample sizes of our products.

We are happy to reassure our customers that all of our products are covered by our Abpromise, which guarantees that the product will work in the applications and species specified on the datasheet, or we will offer a replacement, credit, or refund within 6 months of purchase.

If the product is to be used in an untested species or application, you may be eligible for our testing discount program if the antibody has not yet been purchased. Please do not contact me again by replying to this email prior to purchase for more information. You mention you are using IHC-P (paraffin sections), this is already a tested application so will be covered by the guarantee. However, you also mention cell lines. Are you doing ICC aswell?

Otherwise, we like to encourage all of our customers to submit an Abreview via the online product datasheet. We always appreciate customer feedback, whether positive or negative, and we make all product information available to researchers. Plus, each Abreview earns Abpoints that can be used for discounts on future purchases or rewards such as Amazon.com gift certificates.

I hope this information is helpful. I very much appreciate your patience andwill be in touch again earlier next week with further information for you.

Thank you for contacting us.

Whenthe laboratory characterized thisantibody, there was almost no literature available to compare the staining results with, but now there is some new literature describing the localization of the target protein. The laboratory has decided to re-evaluate this antibody andwe willget back to you whenwe hear the results from the this evaluation.

Attached is also an image we had in colorectal cancer tissue.

Here just FYI - the original test were based on theannotation summary for Normal Human Tissues :

"A majority of normal tissues showed weak to moderate cytoplasmic and nuclear positivity. Strong staining was observed in glandular cells in adrenal cortex and gall bladder. Most cell in CNS and spleen were negative." And for Human Cancer Tissues:
"A majority of colorectal and urothelial cancers showed moderate to strong cytoplasmic and nuclear positivity while a majority of prostate and several breast cancers displayed moderate cytoplasmic staining. Remaining malignancies were weakly stained or negative."

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

Vielen Dank für Ihre Anfrage.

Bisher wurde der ab121794 Anti-B7-H6 antibody leider nicht in ELISA getestet, und auch eine mögliche Kreuzreaktionen mit anderen B7-H Molekülen wurde nicht experimentell untersucht.

Der Antikörper wurde in WB getestet, aber es konnte leider kein Signal detektiert werden:

"The Western blot analysis for each antibody is performed using an identical set up with no optimization, i.e. the same five protein lysates, as well as the same gel type and same conditions are used for all antibodies. As the protein samples and running conditions are not specifically selected and adapted for each antibody and its corresponding protein, not every antibody has been successfully validated for the Western blot application."

Da der Antikörper sein Zielprotein in der IHC erkannte, kann dies ein Indiz dafür sein, dass der Antikörper nur mit dem nativen, nicht-reduzierten Protein reagiert.

Falls Sie dies und den ELISA selbst testen möchten, kann ich Ihnen zur Zeit ein spezielles Angebot über einen 100%igen Abreview-Rabatt anbieten. Bei diesem Angebot bekommen Sie einen Rabatt für eine zukünftige Bestellung, wenn Sie uns ein Abreview mit dem Testresultat des ELISA und/oder WB Experimentes zusenden. Der Rabatt würde den ganzen Wert von ab121794 abdecken, und gegen eine erneute Bestellung eines weiteren primären Antikörpers von uns verrechnet werden.

Um von diesem Angebot profitieren zu können, folgen Sie bitte diesen Schritten:

1.) Bestätigen Sie mir bitte, dass Sie ab121794 in ELISA und/oder WB testen möchten.

2.) Bitte bestellen Sie erst nach Erhalt des Rabattcodes.

3.) Bestellen Sie den Antikörper wie üblich per Telefon, Email oder Fax
