Our Abpromise guarantee covers the use of ab86472 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|Flow Cyt||1/50 - 1/100.
ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
|WB||1/500 - 1/2000. Predicted molecular weight: 39 kDa.|
|IHC-P||1/200 - 1/1000.|
|ICC/IF||1/200 - 1/1000.|
Lanes 1 - 4: Merged signal (red and green). Green - ab86472 observed at 40 kDa. Red - loading control, ab176560, observed at 50 kDa.
ab86472 was shown to recognize Islet 1 in wild-type HAP1 cells as signal was lost at the expected MW in Islet 1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and Islet 1 knockout samples were subjected to SDS-PAGE. ab86472 and ab176560 (Rabbit anti-alpha Tubulin loading control) were incubated overnight at 4°C at 1/500 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preabsorbed ab216772 and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preabsorbed ab216777 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
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.
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.
