  • Anti-Islet 1 antibody [1B1] (ab86501) at 1/500 dilution + full length Islet 1-hIgGFc transfected HEK293 cell lysate

    Predicted band size : 39 kDa
    Observed band size : 80 kDa (why is the actual band size different from the predicted?)
    Note: The molecular weight is larger than expected, as the recombinant protein is not the endogenouse protein, but rather the fc-fusion protein.
  • Confocal immunofluorescence analysis of HEK293 cells trasfected with full-length Islet 1-hIgGFc using ab86501 at 1/150 dilution (green). Blue: DRAQ5 fluorescent DNA dye.

  • IHC image of Islet 1 staining in Human Pancreas formalin fixed paraffin embedded tissue section, performed on a Leica Bond system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab86501, 1/1000 dilution, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

  • Overlay histogram showing SH-SY5Y cells stained with ab86501 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab86501, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG1 [ICIGG1] (ab91353, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive result in SH-SY5Y cells fixed with 4% paraformaldehyde (10 min)/permeabilized in 0.1% PBS-Tween for 20 min used under the same conditions.
