  Western blot - Anti-IKB alpha antibody [E130] (ab32518)

  Lane 1: Wild-type HAP1 whole cell lysate (20 μg)
  Lane 2: IKB alpha knockout HAP1 whole cell lysate (20 μg)
  Lane 3: HeLa whole cell lysate (20 μg)
  

  Lanes 1 - 3: Merged signal (red and green). Green - ab32518 observed at 38 kDa. Red - loading control, ab18058, observed at 130 kDa.

  ab32518 was shown to specifically react with IKB alpha in wild-type HAP1 cells. No band was observed when IKB alpha knockout samples were tested. Wild-type and IKB alpha knockout samples were subjected to SDS-PAGE. ab32518 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 1/10,000 dilution and 1/20,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed (Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed ab216773) and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed (Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed ab216776) secondary antibodies at 1/20,000 dilution for 1 hour at room temperature before imaging.

  Immunocytochemistry/ Immunofluorescence - Anti-IKB alpha antibody [E130] (ab32518)

  Unpurified ab32518 staining IKB alpha in RAW 264.7 (Mouse macrophage cell line transformed with Abelson murine leukemia virus) cells treated with FK506 (FK506 (Tacrolimus), Immunosuppressant ab120223), by ICC/IF. Decrease in IkBα/β expression correlates with increased concentration of FK506, as described in literature.
  The cells were incubated at 37°C for 3h in media containing different concentrations of FK506 (Tacrolimus), Immunosuppressant ab120223 (FK506) 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 ab32518 (1/100 dilution) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight^® 488 goat anti-rabbit polyclonal antibody (Goat Anti-Rabbit IgG H&L (DyLight® 488) preadsorbed ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

  The cells were fixed in 100% methanol (5 min) and then incubated in 1% BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab32518, 1/1000 dilution) overnight at +4°C. The secondary antibody (green) was Alexa Fluor^® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor^® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h.

  Flow cytometry overlay histogram showing wild-type HAP1 (green line) and HAP1-NFKBIA knockout cells stained with ab32518 (magenta line). The cells were fixed with 4% formaldehyde (10 min) and then permeabilised with 0.1% PBS-Triton X-100 for 15 min. The cells were then incubated in 1x PBS containing 10% normal goat serum to block non-specific protein-protein interaction followed by the antibody (ab32518) (1x 10⁶in 100µl at 0.04 µg/ml (1/12500)) for 30min at 22°C.

  The secondary antibody Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed was incubated at 1/4000 for 30min at 22°C

  Isotype control antibody Recombinant Rabbit IgG, monoclonal [EPR25A] - Isotype Control was used at the same concentration and conditions as the primary antibody (wild-type HAP1 - black line, HAP1-NFKBIA knockout - grey line). Unlabelled sample was also used as a control (this line is not shown for the purpose of simplicity).

  Acquisition of >5000 events were collected using a 50 mW Blue laser (488nm) and 525/40 bandpass filter.

  This antibody gave a positive signal in HAP1 WT Fixed with 80% methanol (5 min) / permeabilised with 0.1% PBS-Triton X-100 for 15 min under the same conditions.
