MMP9, also known as Matrix metallopeptidase 9 or gelatinase B is a member of the matrix metalloproteinase (MMP) family. The MMPs are zinc-containing enzymes involved in the degradation of the extracellular matrix in normal physiological processes including embryonic development, reproduction and tissue remodeling. Most MMP family members are secreted as inactive proproteins that become activated when cleaved by extracellular proteinases. The proenzyme MMP9 is thought to be a 92 kDa protein. Processing of the precursor MMP9 yields different active forms, two of which were identified in Duncan et al 1998 (PMID: 9851689) to be 82 kDa and 63 kDa proteins. The 82 kDa protein results from cleavage at the Arg87-Phe88 bond. And the 63 kDa protein is caused by a further cleavage to the 82 kDa protein within the C-terminus domain between Arg527-Gly528. The main 63 kDa protein produced thus has the N-terminus of activated MMP9 and has a cleaved C-terminus. Antibodies specific to the active forms of MMP9 can be useful tools for studying important pathological processes such as tumor invasion, metastasis and arthritis.

FAQs for MMP-9 Antibody (NBP2-13173). (Showing 1 - 2 of 2 FAQs).

  1.  I’m looking for a pair of antibodies to MMP-9 that can be used in a sandwich assay. Do you carry any? 
    • We have 10 primary antibodies for MMP-9 that have been tested in ELISA. looks like 2 have been tested for capture (please note the tested species for each of these). has been tested for detection.
  2. Would it be possible for you to send me your validation data on MMP9 Antibody IIA5 NBP1-40248? I am considering using it in my research project on colorectal cancer liver metastases.
    • Our MMP9 Antibody IIA5 NBP1-40248 was validated in Western blot through external validation, and unfortunately, I do not have an images to share at the moment. NBP2-13173 is another very similar monoclonal antibody validated in human and rat for use in Western blot. We do have images from in-house testing for this product (please see the datasheet for NBP2-13173, under the images tab), so you may be more comfortable ordering this antibody for this target.
