Anti-DDIT3 antibody [9C8] (ab11419)

Western blot analysis of HeLa cell lysates using DDIT3 monoclonal antibody (ab11419). HeLa cells were left untreated (-) or treated with tunicamycin (5μg/ml) for 11 hours (+). Membranes containing whole cell extracts were blocked with 5% milk in TBST (blocking buffer) and probed overnight at 4^oC with ab11419 (diluted 1:2000 in blocking buffer) followed by a goat anti-mouse IgG-HRP secondary antibody (diluted in blocking buffer) and a chemiluminescent substrate. Membranes were also probed for actin as a loading control.

Overlay histogram showing HeLa cells stained with ab11419 (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 (ab11419, 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 IgG2b  (ab91366, 2µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed.

Treated with 20µg/ml poly(I:C).

ab11419 staining DDIT3 in SKNSH cells treated with deltamethrin (ab141019), by ICC/IF. Increase of DDIT3 expression correlates with increased concentration of deltamethrin, as described in literature.
The cells were incubated at 37°C for 48 hours in media containing different concentrations of ab141019 (deltamethrin) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab11419 (10 μg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-mouse polyclonal antibody (ab96879) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
