  • 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.

  • All lanes : Anti-Myc tag antibody [Myc.A7] (ab18185) at 1/1000 dilution

    Lane 1 : Wild-type HEK-293T whole cell lysate
    Lane 2 : MYC knockout HEK-293T whole cell lysate
    Lane 3 : Jurkat whole cell lysate

    Lysates/proteins at 20 µg per lane.

    Observed band size: 48 kDa
    why is the actual band size different from the predicted?

    Lanes 1 - 4: Merged signal (red and green). Green - ab18185 observed at 48 kDa. Red - loading control, ab181602, observed at 37 kDa.

    ab18185 was shown to recognize MYC in wild-type HEK-293T cells as signal was lost at the expected MW in MYC knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and MYC knockout samples were subjected to SDS-PAGE. The membrane was blocked with 3% Milk. Ab18185 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

  • Top Panel: ab18185 staining Myc Tag in rat primary hippocampal neurons by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with paraformaldehyde and blocked with 3% BSA for 15 minutes at 20°C. Samples were incubated with primary antibody (1/200 in PBS-3% BSA) for 30 minutes at 20°C. An Alexa Fluor® 488-conjugated Goat polyclonal to mouse IgG (1/500) was used as secondary antibody.

Thank you for your enquiry,

I am sorry to confirm that the Kd for ab18185 Myc tag antibody [Myc.A7] has not been assessed. It is unusual for the Kd to be measured for research grade antibodies.

We aim to provide as much information as possible to customers, and I am sorry we do not have the details you require on this occasion. If you have any further questions, please do not hesitate to contact us.

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.http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=21719596&dopt=Abstract
