Our Abpromise guarantee covers the use of ab52030 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 Use at an assay dependent concentration. Predicted molecular weight: 181 kDa.
ELISA 1/8000. This antibody can also be used as detection antibody in sandwich ELISA in combination with a polyclonal antibody towards PAPP A in coat.
IHC-P Use at an assay dependent concentration.
IHC-Fr Use at an assay dependent concentration.


  • 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.
