Application

Immunoblotting: 1:1000, identifies a band of approximately 30KDa. Note TIMP-1 is found in very low concentrations in most cells and tissues.Positive control is HT1080 cells treated with PMA or recombinant TIMP-1 protein CC3328.

Immunohistochemistry on frozen sections or acetone fixed tissues. Formalin fixed paraffin-embedded tissue sections are usually not reactive. PLP fixation is suggested as an alternative.

EIA

Optimal working dilutions must be determined by the end user.

Detect TIMP-1 using this Anti-TIMP-1 Antibody, clone 7-6C1 validated for use in ELISA, WB, IH.

General description

Tissue Inhibitors of Metalloproteinases (TIMPs) inhibit the proteolytic invasiveness of tumor cells and normal placental trophoblast cells. TIMP-1 and TIMP-2 have similar properties, specifically in inhibiting enzymes of matrix metalloproteinase family, and are thought to be of great importance in the maintenance of connective tissue integrity. TIMP-1 forms a complex of 1:1 stoichiometry with activated interstitial collagenase, activated stromelysin, active form of 72 kDa type IV collagenase (also known as MMP-2 or gelatinase A), and latent and active forms 92 kDa Type IV collagenase (also known as MMP-9 or gelatinase B). TIMP-1 levels in quiescent cells and tissues is low (pg/ml), and stimulation with the phorbol ester TPA or protein concentration is often needed to visualize protein bands. In addition, cell types differ greatly in the amount of TIMP-1 produced.

Specificity

MAB3300 is a purified mouse monoclonal antibody to bovine tissue inhibitor of metalloproteinases-1 (bovine TIMP-1). The antibody specifically reacts with bovine TIMP-1 and cross-reacts with human and rat TIMP-1, but not with mouse TIMP-1. By western blot the antibody recognizes a glycoprotein of 28.5 kDa, which is identified as tissue inhibitor of metalloproteinases-1 (TIMP-1).

Storage and Stability

Maintain frozen at -20°C in undiluted aliquots for up to 12 months from date of receipt. Avoid repeated freeze-thaw cycles.
