Data Examples
Western Blot | Detection of Human TIMP‑2 by Western Blot. Western blot shows Recombinant Human TIMP-2 Western Blot Standard Protein (Catalog # ) and lysates of HeLa human cervical epithelial carcinoma cell line and human placenta tissue. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human TIMP‑2 Monoclonal Antibody (Catalog # MAB971) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # ). A specific band was detected for TIMP‑2 at approximately 22 kDa (as indicated).This experiment was conducted under reducing conditions and using . |
Immunohistochemistry | TIMP‑2 in Human Ovarian Cancer Tissue. TIMP‑2 was detected in immersion fixed paraffin-embedded sections of human ovarian cancer tissue using 15 µg/mL Mouse Anti-Human TIMP‑2 Monoclonal Antibody (Catalog # MAB971) overnight at 4 °C. Tissue was stained with the Anti-Mouse HRP-AEC Cell & Tissue Staining Kit (red; Catalog # ) and counterstained with hematoxylin (blue). View our protocol for . |

Background: TIMP-2
Tissue inhibitors of metalloproteinases or TIMPs are a family of proteins that regulate the activation and proteolytic activity of the zinc enzymes known as matrix metalloproteinases (MMPs). There are four members of the family, TIMP-1, TIMP-2, TIMP-3, and TIMP-4. TIMP-2 is a non N-glycosylated protein with a molecular mass of 22 kDa produced by a wide range of cell types, which inhibits MMPs non-covalently by the formation of binary complexes. TIMP-2 also has erythroid-potentiating and cell growth promoting activities.
