Our Abpromise guarantee covers the use of ab174314 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
IP 1/10 - 1/100.
IHC-P 1/100 - 1/250. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
WB 1/1000 - 1/10000. Predicted molecular weight: 180 kDa.
  • Application notes
    Is unsuitable for ICC/IF.
  • Target

    • Function
      Metalloproteinase which specifically cleaves IGFBP-4 and IGFBP-5, resulting in release of bound IGF. Cleavage of IGFBP-4 is dramatically enhanced by the presence of IGF, whereas cleavage of IGFBP-5 is slightly inhibited by the presence of IGF.
    • Tissue specificity
      High levels in placenta and pregnancy serum. In placenta, expressed in X cells in septa and anchoring villi, and in syncytiotrophoblasts in the chorionic villi. Lower levels are found in a variety of other tissues including kidney, myometrium, endometrium, ovaries, breast, prostate, bone marrow, colon, fibroblasts and osteoblasts.
    • Sequence similarities
      Belongs to the peptidase M43B family.
      Contains 5 Sushi (CCP/SCR) domains.
    • Developmental stage
      Present in serum and placenta during pregnancy; levels increase throughout pregnancy.
    • Post-translational
      There appear to be no free sulfhydryl groups.
