  • Target

    • FunctionProbable role in assembly and expression of the TCR complex as well as signal transduction upon antigen triggering.
    • Involvement in diseaseDefects in CD247 are the cause of immunodeficiency due to defect in CD3-zeta (CD3ZID) [MIM:610163]. An immunological deficiency characterized by T-cells impaired immune response to alloantigens, tetanus toxoid and mitogens.
    • Sequence similaritiesBelongs to the CD3Z/FCER1G family.
      Contains 3 ITAM domains.
    • DomainThe ITAM domains mediate interaction with SHB.
    • Post-translational
      Phosphorylated on Tyr residues after T-cell receptor triggering.
    • Cellular localizationMembrane.

    We do not have any more of ab11505 in stock. Are you able to use the PE-conjugated version of the same clone, ab33395, or the unconjugated version, ab11218? Alternatively, we have a FITC-conjugated hamster monoclonal antibody that is raised against mou...

    Thank you for your reply.

    Unfortunately, I am sorry to confirm that I have checked the CD3 zeta antibodies that have been tested in flow cytometry and human samples. These have epitopes in the cytoplasmic domain, and so would require permeab...

    Thank you for your enquiry.

    I have done some literature searching and am not able to find any information to indicate that the membrane and cytoplasmic forms of CD3 Zeta are different, apart from the localization. Therefore, I would suggest ...

    Thank you for your response.

    ab97077 is a goat anti-rabbit secondary so it is unlikely to react with ab91493 (host species hamster). However, ab97037 is goat anti-mouse secondary antibody and it may cross-react with hamster IgG since mouse an...

    Thank you for your enquiry.

    Could you please confirm if the customer would like to perform double or triple staining? I am a bit confused why the two selected secondary antibodies ie ab97037 and ab97077 (Cy5 ®) have the same fluorophore? ...
