  • Relevance
    Human influenza hemagglutinin (HA) is a surface glycoprotein required for the infectivity of the human virus. The HA tag is derived from the HA molecule corresponding to amino acids 98-106 has been extensively used as a general epitope tag in expression vectors. Many recombinant proteins have been engineered to express the HA tag, which does not appear to interfere with the bioactivity or the biodistribution of the recombinant protein. This tag facilitates the detection, isolation, and purification of the proteins.

  • ab9110 was diluted to 4 µg/mg lysate and incubated with a nuclear lysate of HEK293T cells transiently expressing HA-tagged protein and a Protein A matrix for 2 hours a 23°C to achieve immunoprecipitation.  1000 µg of lysate was present in the input. 

    A HRP-conjugated anti-rabbit HA monoclonal antibody diluted 1/1000 was used for the Western Blot step.

  • This image was kindly supplied as part of the review submitted by Kasper Fugger. Immunofluorescence staining of U-2 cells expressing HA-tagged protein with ab9110.
  • Xenopus laevis oocytes were injected with mRNA for HA-tagged human BORIS. Chromatin was prepared according to the Abcam X-ChIP protocol. Oocytes were fixed with formaldehyde for 10min. The  ChIP was performed with 25µg of chromatin, 20µl of Protein A/G sepharose beads, and 3µg of ab9110 (anti-HA, light blue) or, 3µg of ab18337 (anti-Boris, dark blue). A non-specific antibody was used as a control (yellow). The immunoprecipitated DNA was quantified by real time PCR (Taqman approach).

  • ab 9110 at a 1/200 dilution staining the mouse olineu cell line (oligodendrocyte precursor cell) by immunocytochemistry. The antibody was incubated with the cells for 30 minutes and then detected using a Cy5 conjugated goat anti-rabbit antibody.

Customer reviews and Q&As

My colleagues confirmed the antibody is non reactive with KLH and non transfected cells.

Although we have not tested this antibody specifically against proteins expressed in S. cerevisiae, it should recognise the protein in this species.

I have to confirm that we did not test ab9110 with multiple HA tag repeats in CHIP but only with a single tag.

But I would expect ab9110 to work also with multiple HA tag repeats.

Multiple freeze-thaw cycles may reduce the activity of this antibody. If you are concerned about losing activity by freezing this antibody, it can be stored in 50% glycerol at -20C. This will keep the antibody from freezing while allowing it to be stor...

I can confirm that this primary antibody (ab9110) can be used for ELISA. Since it is not labelled it is important to use a compatible secondary antibody for detection which is conjugated to either to an enzyme or to a fluorochrome.

Yes, ab9110 is the unconjugated form of ab26228 (biotinylated form).

Both antibodies have not yet been tested in any IHC application (neither IHC-P or IHC-Fr).

Yes, you are correct, this antiserum was validated using our unique system of HA-tagging BORIS and injecting into Xenopus oocytes. The antiserum has not yet been tested by ChIP in human cells. However, this antiserum was tested by ChIP using the stan...

Under the IF suggested dilution range for this antibody, the 1:40,000 dilution was a typo - it was supposed to be 1:4000. We have received some nice feedback from customers who have used this antibody in IF, and several have mentioned obtaining good re...
