  • Relevance
    Epitope tags are short peptide sequences that are easily recognized by tag-specific antibodies. Due to their small size, epitope tags do not affect the tagged protein’s biochemical properties. Most often sequences encoding the epitope tag are included with target DNA at the time of cloning to produce fusion proteins containing the epitope tag sequence. This allows anti-epitope tag antibodies to serve as universal detection reagents for any tag containing protein produced by recombinant means. This means that anti-epitope tag antibodies are a useful alternative to generating specific antibodies to identify, immunoprecipitate or immunoaffinity purify a recombinant protein. The anti-epitope tag antibody is usually functional in a variety of antibody-dependent experimental procedures. Expression vectors producing epitope tag fusion proteins are available for a variety of host expression systems including bacteria, yeast, insect and mammalian cells.

  • Y. enterocolitica ΔHOPEMT carrying plasmids encoding Myc-tagged CT082 or CT695, and HA-tagged Slc1 (as indicated) were grown in non-secreting conditions. Chloramphenicol was added (time?=?0 min) to stop bacterial protein synthesis and samples were taken at the indicated time points. Samples were analyzed by immunoblotting using ab9106, anti-HA, and anti-TEM antibodies.

  • ab9106 staining the Myc tag in HeLa (Human epithelial cell line from cervix adenocarcinoma) cells transfected with a Myc-tagged membrane targeting protein by ICC/IF (Immunocytochemistry/immunofluorescence).

    Cells were fixed with paraformaldehyde, permeabilized with Triton X (0.5%) and blocked with 3% BSA for 1 hour at 24°C. Samples were incubated with primary antibody (1/500) for 1 hour at 24°C. An Alexa Fluor®488-conjugated Goat anti-rabbit polyclonal was used as the secondary antibody.

    Cells expressed myc-tagged CDC42 protein. Immunoprecipitation step performed using Protein A matrix. Incubation time 4 hours at 4°C. Western Blot antibody used at 1/300 dilution.

  • ab9106 used at 1/250 in the immunoprecipitation of transfected human 293FT cells (whole cell lysate).

    In this experiment cells were co-transfected with myc tagged cdc25 along with an HA tagged viral protein which binds to cdc25. The cell lysate was immunoprecipitated using ab9106, run on a 10% gel. The blot was probed for HA and HA tagged protein (which co-IPed with Myc tagged protein) and this is seen at ~15KDa.

Thank you for your email. I am sorry to hear that you have been experiencing problems with this antibody.

I have read the details you have kindly provided and have following further questions for better understanding of the problem;

- Antibodies usually are OK for about a week at room temperature which however varies from product to product so for how long this antibody was delayed in shipment?
- How do you define the problem? Is it no band, high background or multiple band etc?
- The antibody is against myc tag so have you used the antibody against protein of interest? How were the results?
- Could you provide an image?

Thank you very much for your cooperation. I will look forward to hearing from you soon.

Thank you for contacting us.

From the looks of it, this is not a suitable antibody for you, as it is only suitable for the tag (only a few AA long)but not for the c-Myc protein (48 kDa). I checked the sequence and it looks like this antibody coulddetect c-Myc, but there may be a lot of other cross-reactivity as the sequence is so short.Fortunately, we have a few c-Myc antibodies in our catalogue. I picked three antibodies with the best ratings for your applications and the most publications: (or use the following: (or use the following: (or use the following:

Thank you for getting back to me and for providing some further information about your research project.

Currently, we have 2 monoclonal antibodies against Myc tag: ab18185 and ab94936. Although they are from the same clone but from two sources and the testing conditions were different. ab94936 reacts with recombinant fragment so the other antibody ab18185 may suit your need better.

There are two specific publication for ab18185 you could take a look at to get some more information:

Biswas Ket al. A comprehensive functional characterization of BRCA2 variants associated with Fanconi anemia using mouse ES cell-based assay. Blood 118:2430-42 (2011). WB.
Ohe Met al. Emi2 inhibition of the anaphase-promoting complex/cyclosome absolutely requires Emi2 binding via the C-terminal RL tail. Mol Biol Cell 21:905-13 (2010). WB.

If you need any further assistance in the future, please do not hesitate to contact me.

Thank you for your enquiry and interest in our products.

Could you please let me know if you wish to detect a Myc tagged protein or myc itself? For what application you are looking for the alternative antibodies and what type of samples you are using? Is there any reason why you wish to switch from ab9106 to another antibody? Any additional information you could provide would help me advise some alternative products for you.

I look forward to hearing from you soon.

I'm afraid I have received very little information from the source of ab9106. I was informed just a few minutes ago " a customer of mine had sent me the anti-Myc image, but only provided me with the working dilution. I have been unable to track them down at their university". I am therefore unable to find out what type of fixative was used. For ab32, the information that it works in IF dates from 2001, where a customer told us it worked well for him. At the time we did not request further details and therefore unfortunately again we do not know if 4%PFA was the fixative successfully used. If you are able to try different fixatives on your cells I would therefore recommend to try both 4% PFA and acetone as fixatives and see which one works well for you. If you cannot have your cells fixed in anything other than 4% PFA I would recommend not to purchase these products as I'm not sure they will work with 4% PFA. I would be happy to enquire if ab9132 will work on 4% PFA fixed cells, however the detection method was chromogenic, not fluorescent, therefore the antibody may or may not work in IF, we don't know at this stage. I'm sorry I cannot help you more on this occasion,

Thank you for your enquiry. The comparison of the amino acid of the sequence used to generate this antibody with the full-length precursor of mouse myc (primary accession number P01108) shows 70% identity. The file for this comparison can be found at this link for the next 24 hours: Recognition of mouse myc by this antibody, given the 70% identity, is difficult to predict. However, two of the amino acid pairs consist of biochemically similar amino acids(designated by the ":" symbol in this alignment tool), and the antibody is polyclonal, so it will potentially recognize more than one epitope on the sequence. If you decide to try the antibody to detect endogenous mouse myc, we would appreciate your feedback. We have a rewards incentive for reviews of our antibodies called Abpoints, the details of which can be found on our website. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry. This antibody was tested for quality control by loading 50 ng of tagged protein per well. I think it would detect lower concentrations but I would suggest a starting dilution of 2 ug/ml of antibody and increase the normal incubation period from 60 min to 120 min. I hope this information helps. Please do not hesitate to contact us if you need anything further.
