  • Function
    Mitochondrial membrane ATP synthase (F(1)F(0) ATP synthase or Complex V) produces ATP from ADP in the presence of a proton gradient across the membrane which is generated by electron transport complexes of the respiratory chain. F-type ATPases consist of two structural domains, F(1) - containing the extramembraneous catalytic core, and F(0) - containing the membrane proton channel, linked together by a central stalk and a peripheral stalk. During catalysis, ATP synthesis in the catalytic domain of F(1) is coupled via a rotary mechanism of the central stalk subunits to proton translocation. Subunits alpha and beta form the catalytic core in F(1). Rotation of the central stalk against the surrounding alpha(3)beta(3) subunits leads to hydrolysis of ATP in three separate catalytic sites on the beta subunits.
  • Sequence similarities
    Belongs to the ATPase alpha/beta chains family.
  • Cellular localization
    Mitochondrion. Mitochondrion inner membrane. Peripheral membrane protein.

    Merged signal (red and green). Green - ab14730 observed at 52 kDa. Red - loading control, ab181602 observed at 37 kDa.

    Samples were subjected to SDS-PAGE. ab14730 and ab181602 (Rabbit anti-GAPDH loading control) were incubated overnight at 4°C at 1ug/mL and 1/10000 dilution respectively. Blots were developed with Goat anti-Mouse IgG H&L (IRDye® 800CW) preadsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye® 680RD) preadsorbed (ab216777) secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.

  • ab14730 staining ATPB in cultured human fibroblasts. Cells were fixed, permeabilized and then labelled with ab14730 followed by an AlexaFluor® 488-conjugated Goat anti-Mouse IgG1-specific secondary antibody (2 µg/ml)
  • ab14730 (2µg/ml) staining ATPB in human duodenum using an automated system (DAKO Autostainer Plus). Using this protocol there is cytoplasmic and mitochondrial staining of epithelium.
    Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.

Thank you for your enquiry. The epitopes have not been determined for these two monoclonal antibodies. Ab5432 and ab14730 are different clones, and ab5432 was made using intact rat mitochondria as the immunogen, whereas human whole heart mitochondria was used as the immunogen for ab14730. Ab5432 was tested for application in IP and IF, and ab14730 was tested for application in Western blot and Immunocytochemistry. Please contact us again if you have any additional questions.
