Our Abpromise guarantee covers the use of ab28469 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
WB Use a concentration of 0.25 µg/ml. Predicted molecular weight: 45-55 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA 1/2500.
ICC/IF Use a concentration of 5 µg/ml.


  • FunctionIon channel gated by extracellular ATP involved in a variety of cellular responses, such as excitatory postsynaptic responses in sensory neurons, neuromuscular junctions (NMJ) formation, hearing, perception of taste and peristalsis. In the inner ear, regulates sound transduction and auditory neurotransmission, outer hair cell electromotility, inner ear gap junctions, and K(+) recycling. Mediates synaptic transmission between neurons and from neurons to smooth muscle.
  • Involvement in diseaseDeafness, autosomal dominant, 41
  • Sequence similaritiesBelongs to the P2X receptor family.
  • Cellular localizationCell membrane. Localizes to the apical membranes of hair cells in the organ of Corti.

  • Predicted band size : 45-55 kDa
    Observed band size : 49,55 kDa (why is the actual band size different from the predicted?)
  • ICC/IF image of ab28469 stained PC12 cells. The cells were 4% formaldehyde (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab28469, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899 Dylight 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
