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

Application Abreviews Notes
WB 1/1000 - 1/10000. Detects a band of approximately 40 kDa (predicted molecular weight: 32 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
  • Application notes
    Is unsuitable for Flow Cyt,ICC or IP.
  • Target

    • Function

      This is the non-catalytic component of the active enzyme, which catalyzes the hydrolysis of ATP coupled with the exchange of Na(+) and K(+) ions across the plasma membrane. The exact function of the beta-3 subunit is not known.
    • Sequence similarities

      Belongs to the X(+)/potassium ATPases subunit beta family.
    • Cellular localization

      Membrane. Melanosome. Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
