Our Abpromise guarantee covers the use of ab977 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.
WB 1/1000 - 1/5000. Incubate for 1 hour at room temperature. Background can be reduced by adding NaCl up to a concentration of 1.5M.
ICC/IF 1/1000. Incubate for 1 hour at room temperature.


  • RelevanceThe E2Tag is a peptide which is derived from the Bovine Pappillomavirus type-1 transactivator protein E2 and consists of 10 amino acids(SSTSSDFRDR). The detection of E2-tagged proteins is based on the binding of mouse monoclonal antibodies specific to the tagged recombinant protein.

Anti-E2 tag antibody [5E11] images

  • Cos-7 cell lysates (1µg of total protein per lane) were transfected with pQM vectors encoding two different E2-tagged proteins. Detection is performed with anti-E2Tag antibody (5E11) (1:10 000 in TBST) with and without high salt followed by incubation with goat anti-mouse HRP conjugate (1:10,000).
  • ab977 at 1/200 dilution staining human Hela cells by ICC/IF. The HeLa cells were transfected with the fusion DNA construct pQM-NTag/A consisting of E2 tag fused in frame with gene specific cDNA. The cells were fixed with paraformaldehyde and blocked with serum prior to incubation with the antibody for 2 hours. A Cy3 conjugated sheep anti-mouse IgG antibody was used as the secondary.
