Our Abpromise guarantee covers the use of ab66793 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IP Use at an assay dependent dilution.
ICC/IF Use at an assay dependent dilution.
WB Use a concentration of 0.2 - 1 µg/ml. Detects a band of approximately 20-28 kDa (predicted molecular weight: 23 kDa).


  • Function

    May be involved in macrophage-mediated cellular proliferation. It is mitogenic for fibroblasts and smooth muscle but not endothelial cells. It is able to bind EGF receptors with higher affinity than EGF itself and is a far more potent mitogen for smooth muscle cells than EGF. Also acts as a diphtheria toxin receptor.
  • Sequence similarities

    Contains 1 EGF-like domain.
  • Post-translational

    Several N-termini have been identified by direct sequencing. The forms with N-termini 63, 73 and 74 have been tested and found to be biologically active.
    O-linked glycan attachment sites were determined by Edman degradation, O-glycanase digest suggests mucin-type glycosylation (done in HB-EGF purified from histiocytic lymphoma cell line U-937).
  • Cellular localization

    Cell membrane and Secreted > extracellular space. Mature HB-EGF is released into the extracellular space and probably binds to a receptor.

Thank you for your inquiry. You probably could use an anti-mouse secondary antibody with ab66793 since we know it worked well with a Cy3-conjugated secondary antibody. But, there are 7.5 biotin molecules per IgG1 molecule, and that could cause a lot of hindrance to block the binding of the secondary antibody. We do have anti-biotin conjugated antibodies (if that's what you are looking for), such as Anti-Biotin (Alkaline Phosphatase) ab6652, Anti-Biotin (HRP) ab19221, and Anti-Biotin (FITC) ab6650.

Click here (or use the following: https://www.abcam.com/index.html?datasheet=6650). What is probably best to do is to use a strepatvidin conjugate to bind the biotin on ab66793. We have two (peroxidase and AP). https://www.abcam.com/Streptavidin-Peroxidase-Ready-to-Use-ab64269.html https://www.abcam.com/Streptavidin-Alkaline-Phosphatase-Ready-to-Use-ab64268.html I hope this information helps.

We could not find the sequence of Macaque monkey HB-EGF in databases. However, since the green monkey HB-EGF sequence has 97% identity to that of human, there is a good chance that ab66793 react with Macaque HB-EGF. Though the human HB-EGF has 80% identity with that of mouse and ab66793 did not react with mouse HB-EGF.
