  • Anti-Islet 1 antibody [1H9] (ab86472) at 1/500 dilution + HEK293 cells transfected with full length Islet 1 (aa1-349)-hIgGFc

    Predicted band size : 39 kDa

    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 ab86472 at 1/150 dilution (green). Blue: DRAQ5 fluorescent DNA dye.

  • ab86472 at a 1/200 dilution staining Islet 1 in human lung cancer tissue. DAB staining shows nuclear localisation.
  • ab86472 at a 1/200 dilution staining Islet 1 in human cervical carcinoma tissue. DAB staining shows nuclear localization.
  • Overlay histogram showing SH-SY5Y cells stained with ab86472 (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 (ab86472, 1/50 dilution) 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/1x10^6 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.
