Detects human MMP-7 in direct ELISAs and Western blots. In direct ELISAs, approximately 50% cross-reactivity with recombinant mouse MMP-7 is observed, and less than 1% cross-reactivity with recombinant human (rh) MMP‑8 and rhMMP-12 is observed.
Polyclonal Goat IgG
Mouse myeloma cell line NS0-derived recombinant human MMP‑7 Leu18-Lys267 Accession # P09237
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Measured by its ability to neutralize Recombinant Human MMP‑7 (0.2 µg/mL, Catalog # 907-MP) cleavage of the fluorogenic peptide substrate Mca-PLGL-Dpa-AR-NH2 (10 µM, Catalog # ES001). The Neutralization Dose (ND50) is typically 2 µg/mL.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Neutralization of MMP‑7 Activity by Human MMP‑7 Antibody. The cleavage of Mca‑PLGL‑Dpa‑AR‑NH2 (10 μM, Catalog # ES001) by Recombinant Human MMP‑7 (0.2 µg/mL, Catalog # 907-MP) is measured after preincubation with increasing concentrations of Goat Anti-Human MMP‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF907). The ND50 is typically 2 µg/mL.
Detection of Human MMP‑7 by Western Blot. Western blot shows lysates of Capan‑1 human pancreatic adenocarcinoma cell line and HT‑29 human colon adenocarcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human MMP‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF907) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for MMP‑7 at approximately 28 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
MMP‑7 in Human Pancreas. MMP‑7 was detected in immersion fixed paraffin-embedded sections of human pancreas array using Goat Anti-Human MMP‑7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF907) at 10 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Lower panel shows a lack of labeling if primary antibodies are omitted and tissue is stained only with secondary antibody followed by incubation with detection reagents.

Matrix metalloproteinases (MMPs) are a family of zinc and calcium dependent endopeptidases with the combined ability to degrade all the components of the extracellular matrix. MMP-7 (matrilysin) is expressed in epithelial cells of normal and diseased tissues, and is capable of digesting a large series of proteins of the extracellular matrix including collagen IV and X, gelatin, casein, laminin, aggrecan, entactin, elastin and versican. MMP-7 is implicated in the activation of other proteinases such as plasminogen, MMP-1, MMP-2, and MMP-9. In addition to its roles in connective tissue remodeling and cancer, MMP-7 also regulates intestinal alpha ‑defensin activation in innate host defense, releases tumor necrosis factor‑ alpha in a model of herniated disc resorption, and cleaves FasL to generate a soluble form in a model of prostate involution. Structurally, MMP-7 is the smallest of the MMPs and consists of two domains: a pro-domain that is cleaved upon activation and a catalytic domain containing the zinc-binding site.
