Our Abpromise guarantee covers the use of ab124874 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 1/1000 - 1/10000. Detects a band of approximately 55, 48, 27 kDa (predicted molecular weight: 52 kDa). Note: The 48-kDa form is generated by proteolytic cleavage at the C-terminus. This subunit is cleaved into a peptide
ICC/IF 1/100 - 1/250.
  • Application notes
    Is unsuitable for Flow Cyt,IHC-P or IP.
  • Target

    • Function

      Protects the body from potent vasoactive and inflammatory peptides containing C-terminal Arg or Lys (such as kinins or anaphylatoxins) which are released into the circulation.
    • Tissue specificity

      Synthesized in the liver and secreted in plasma.
    • Involvement in disease

      Defects in CPN1 are the cause of carboxypeptidase N deficiency (CPND) [MIM:212070]. Patients affected present some combination of angioedema or chronic urticaria, as well as hay fever or astma, and have also slightly depressed serum carboxy peptidase N, suggestive of autosomal recessive inheritance of this disorder.
    • Sequence similarities

      Belongs to the peptidase M14 family.
    • Cellular localization

      Secreted > extracellular space.
