All lanes : Goat Anti-Mouse IgG H&L (HRP) preadsorbed (ab97040) at 1/5000 dilution

Developed using the ECL technique.

Performed under reducing conditions.

Predicted band size: 110 kDa
Observed band size: 100 kDa why is the actual band size different from the predicted?
Additional bands at: 25 kDa, 70 kDa. We are unsure as to the identity of these extra bands.


Exposure time: 8 minutes


The 100 kDa band observed is comparable to the molecular weight seen with other commercially available antibodies to alpha 1 Sodium Potassium ATPase.

Immunocytochemistry/Immunofluorescence analysis of alpha 1 Sodium Potassium ATPase (green) in HeLa cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 15 minutes at room temperature and blocked with 0.3% BSA for 15 minutes at room temperature. Cells were incubated with ab2872 (1:100) for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (1:500) for 30 minutes at room temperature. F-actin (red) was stained with DyLight 594 Phalloidin and nuclei (blue) were stained with Hoechst 33342 dye. Images were taken at 20X magnification.

ab2872 staining pig hepatocyte tissue sections by IHC-P.  The section was fixed with Bouins and subjected to heat mediated antigen retrieval (at pH 9) prior to incubating with the primary antibody, diluted 1/2000, for 1 hour at 20°C.  A Cy3® conjugated goat anti-mouse IgG antibody was used as the secondary.

Overlay histogram showing HEK293 cells stained with ab2872 (red line). The cells were fixed with 100% methanol (5 min) and incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab2872, 1/100 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/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in HEK293 cells fixed with 4% paraformaldehyde used under the same conditions.

Please note that Abcam do not have any data for use of this antibody on non-fixed cells. We welcome any customer feedback.

Immunohistochemistry was performed on both normal and cancer biopsies of deparaffinized Human tonsil tissue tissues. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1:50 with a mouse monoclonal antibody recognizing Sodium/Potassium ATPase alpha-1 ab2872 or without primary antibody (negative control) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.
