    ab133600 was shown to react with CBFb in wild-type A431 cells in western blot. Loss of signal was observed when CBFB knockout sample was used. Membranes were blocked in 2 % BSA in TBS-T (0.1 % Tween®) before incubation with ab133600 overnight at 4°C at a 1 in 1000 dilution and ab184095 (Mouse Anti-GAPDH antibody [mAbcam 9484] - Alexa Fluor® 680) at a 1 in 1000 dilution. Blots were incubated with HRP conjugated Goat anti-Rabbit (H+L) secondary antibody at 1/5000 for 1 hour at room temperature before development with Optiblot ECL reagent (ab133456) and imaging.

    Immunocytochemistry/Immunofluorescence analysis of Jurkat (Human T cell leukemia T lymphocyte) cells labeling CBFb with purified ab133600 at 1/100 dilution (10 µg/mL). Cells were fixed in 100% Methanol and permeabilized with None. Cells were counterstained with Ab195889 Anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) 1/200 (2.5 µg/mL). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) was used as the secondary antibody at 1/1000 (2 µg/mL) dilution. DAPI (blue) was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control.

    Lanes 1 - 4: Merged signal (red and green). Green - ab133600 observed at 22 kDa. Red - loading control ab7291 (Mouse anti-Alpha Tubulin [DM1A]) observed at 55kDa.

    ab133600 was shown to react with CBFb in wild-type A431 cells in western blot with loss of signal observed in CBFB knockout sample. Wild-type and CBFB knockout A431 cell lysates were subjected to SDS-PAGE. Membranes were blocked in 2% BSA in TBS-T (0.1% Tween®) before incubation with ab133600 and ab7291 (Mouse anti-Alpha Tubulin [DM1A]) overnight at 4°C at a 1 in 1000 Dilution and a 1 in 20000 dilution respectively. Blots were incubated with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) secondary antibodies at 1 in 20000 dilution for 1 hour at room temperature before imaging.
