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. Predicted molecular weight: 42 kDa.
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC 1/50 - 1/100.
  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      Controls phosphatidylcholine synthesis.
    • Pathway
      Phospholipid metabolism; phosphatidylcholine biosynthesis; phosphatidylcholine from phosphocholine: step 1/2.
    • Sequence similarities
      Belongs to the cytidylyltransferase family.
    • Post-translational
      The serine residues of the C-terminus are phosphorylated. The inactive soluble form is stabilized by phosphorylation, the active membrane bound form is promoted by anionic lipids or diacylglycerol, and is stabilized by dephosphorylation.
    • Cellular localization
      Cytoplasm > cytosol. Membrane. It can interconvert between an inactive cytosolic form and an active membrane-bound form.
