Scientific Data Images for Human/Mouse TIMP-2 Antibody
Detection of Human TIMP‑2 by Western Blot.
Western blot shows Recombinant Human TIMP-2 Western Blot Standard Protein (Catalog # WBC023) and lysates of HeLa human cervical epithelial carcinoma cell line and human placenta tissue. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse TIMP-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF971) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for TIMP-2 at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
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 Goat Anti-Human/Mouse TIMP-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF971) overnight at 4 °C. Tissue was stained with the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counter-stained with hematoxylin (blue).

Western Blot Shows Human TIMP-2 Specificity by Using Knockout Cell Line.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line and human TIMP-2 knockout HeLa human cervical epithelial carcinoma cell line (KO). PVDF membrane was probed with 1 µg/mL of Goat Anti-Human/Mouse TIMP-2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF971) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (HAF017). A specific band was detected for TIMP-2 at approximately 22 kDa (as indicated) in the parental HeLa human cervical epithelial carcinoma cell line, but is not detectable in knockout HeLa human cervical epithelial carcinoma cell line. GAPDH (AF5718) is shown as a loading control. This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.Applications for Human/Mouse TIMP-2 Antibody

Neutralization
Measured by its ability to neutralize Recombinant Human TIMP-2 (0.143 µg/mL, Catalog # 971-TM) inhibition of Recombinant Human MMP‑2 (0.2 µg/mL, Catalog # 902-MPN or 902-MP) cleavage of the fluorogenic peptide substrate Mca‑PLGL‑Dpa‑AR‑NH2 (10 µM, Catalog # ES001). The Neutralization Dose (ND50) is typically 2.6 µg/mL.

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.
