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 84 kDa (predicted molecular weight: 85 kDa).
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
IP 1/10 - 1/100.
  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function

      Protein phosphatase that inactivates multifunctional CaM kinases such as CAMK4 and CAMK2 (By similarity). Dephosphorylates and inactivates PAK. May play a role in the inhibition of actin fiber stress breakdown and in morphological changes driven by TNK2/CDC42.
    • Sequence similarities

      Belongs to the PP2C family.
      Contains 1 PP2C-like domain.
    • Cellular localization

      Nucleus. Cytoplasm. A truncated form, major form, with the C-terminal part missing, is mostly found in the cytoplasm and a little in the nucleus. The full length, minor form, is found in the nucleus.
