Detects both the pro and active forms of human MMP-3 in direct ELISAs and Western blots. In direct ELISAs, 50‑100% cross-reactivity with recombinant mouse MMP-3 is observed, 10% cross-reactivity with recombinant human (rh) MMP-10 is observed and no cross-reactivity with rhMMP-1, -2, -7, -8, -9, -12 or -13 is observed.

Detection of Human MMP‑3 by Western Blot.
Western blot shows Recombinant Human MMP-3 Westrern Blot Standard Protein (2 μL, Catalog # WBC015). PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human MMP‑3 Monoclonal Antibody (Catalog # MAB513) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for MMP‑3 at approximately 55 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
MMP‑3 in Human Prostate and Human Prostate Cancer Tissue.
MMP‑3 was detected in immersion fixed paraffin-embedded sections of normal human prostate and human prostate cancer tissue using Mouse Anti-Human MMP‑3 Monoclonal Antibody (Catalog # MAB513) at 15 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). Specific staining was localized to cytoplasm in cancer cells (right panel). View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
MMP‑3 in MG-63 Human Cell Line.
MMP‑3 was detected in immersion fixed MG-63 human osteosarcoma cell line using 10 µg/mL Mouse Anti-Human MMP‑3 Monoclonal Antibody (Catalog # MAB513) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

Detection of MMP‑3 in MG‑63 Human Cell Line by Flow Cytometry.
MG‑63 human osteosarcoma cell line was stained with Mouse Anti-Human MMP‑3 Monoclonal Antibody (Catalog # MAB513, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005). View our protocol for Staining Intracellular Molecules.

Matrix metalloproteinases are a family of zinc and calcium dependent endopeptidases with the combined ability to degrade all the components of the extracellular matrix. MMP-3 (stromelysin-1), can degrade a broad range of substrates including collagen alpha chains, aggrecan, laminin, fibronectin, elastin, casein, alpha -1 antitrypsin, myelin basic protein, IL-1 beta, IGFBP-3, pro MMP-1, pro MMP-7, pro MMP-8, pro MMP-9 and pro MMP-13. MMP-3 does not cleave the triple helical region of interstitial collagens, a characteristic which distinguishes the stromelysins from the collagenases. The MMP-3 substrate repertoire extends beyond extracellular matrix proteins and implicates MMP-3 in roles other than direct tissue remodelling, for instance, enzyme cascades and cytokine regulation. MMP-3 is expressed by fibroblasts, chrondrocytes, osteoblasts, endothelial cells, smooth muscle cells and macrophages. Structurally, MMP-3 may be divided into several distinct domains; a pro-domain which is cleaved upon activation; a catalytic domain containing the zinc binding site; a short hinge region and a carboxyl terminal (hemopexin-like) domain.
