  • Function

    This magnesium-dependent enzyme catalyzes the hydrolysis of ATP coupled with the transport of calcium out of the cell.
  • Tissue specificity

    Isoform XB is the most abundant isoform and is expressed ubiquitously. Isoforms containing segment Z have only been detected in heart, while isoforms containing segment a have been found in heart, stomach and brain cortex.
  • Sequence similarities

    Belongs to the cation transport ATPase (P-type) (TC 3.A.3) family. Type IIB subfamily.
  • Cellular localization

    Cell membrane.

  • IHC image of ab2783 staining in human cervical carcinoma formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab2783, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

  • Overlay histogram showing HeLa cells stained with ab2783 (red line). The cells were fixed with 80% 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 (ab2783, 2μg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. 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.
    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 normal biopsies of deparaffinized Human brain tissue. 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 1:100 with a mouse monoclonal antibody recognizing PMCA4 ATPase ab2783 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.

Thank you for contacting us.

ab2825 can be used in flow cytometry and is positively tested however for detection you would need a Fluorophore conjugated anti mouse secondary antibody. Please click the below link for protocol;


The compatible secondary antibodies are





We have tested ab2783 with Hela cells and is fully guaranteed for all Rat and human cells require they express the protein. Human erythrocytes can be used with this antibody.

ab2825 has been tested with human Jurkat and monocytic cells so it will work with all PMCA4 expressing human cells.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
