Immunocytochemistry/ Immunofluorescence - Anti-CBFb antibody [EPR6322] - BSA and Azide free (AB248572)

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.

This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab133600).

Flow Cytometry (Intracellular) - Anti-CBFb antibody [EPR6322] - BSA and Azide free (AB248572)

Intracellular Flow Cytometry analysis of K-562 (Human chronic myelogenous leukemia lymphoblast) cells, labeling CBFb with purified ab133600 at 1/100 dilution (10μg/mL) (Red). Cells were fixed with 4% Paraformaldehyde and permeabilised with 90% Methanol. A Goat anti rabbit IgG (Alexa Fluor^®488, ab150077) secondary antibody was used at 1/2000. Isotype control - Rabbit monoclonal IgG (Black). Unlabeled control - Cell without incubation with primary antibody and secondary antibody (Blue). This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab133600).

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.

Western blot - Anti-CBFb antibody [EPR6322] - BSA and Azide free (AB248572)

This data was developed using the same antibody clone in a different buffer formulation (ab133600).

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.
