Detects mouse TIMP-1 in direct ELISAs and Western blots. In direct ELISAs, approximately 15% cross-reactivity with recombinant rat TIMP-1 is observed, less than 5% cross-reactivity with recombinant human (rh) TIMP-1 is observed, and less than 1% cross-reactivity with rhTIMP-2 is observed.
Measured by its ability to neutralize Recombinant Mouse TIMP-1 (0.07 µg/mL, Catalog # 980-MT) inhibition of Recombinant Mouse/Rat MMP‑2 (0.2 µg/mL, Catalog # 924-MP) cleavage of the fluorogenic peptide substrate Mca-PLGL-Dpa-AR-NH2 (10 µM, Catalog # ES001). The Neutralization Dose (ND50) is typically 1.3 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.

Tissue inhibitors of metalloproteinases or TIMPs are a family of homologous proteins that regulate the activity of matrix metalloproteinases (MMPs) (1, 2). There are four known members of the family, TIMP-1, TIMP-2, TIMP-3, and TIMP-4 that have been found to exhibit multiple functions, including inhibition of active MMPs, pro‑MMP activation, cell growth promotion, matrix binding, inhibition of angiogenesis and the induction of apoptosis. Structurally, TIMPs have two domains, an N‑terminal domain and a C-terminal domain. Each domain consists of three disulfide-bonded loops. TIMP-1 is a glycoprotein produced by a wide range of cell types. Through its N-terminal domain, TIMP-1 inhibits active MMPs by forming a non-covalent binary complex with the MMP active site. The C-terminal domain of TIMP‑1 interacts with the C-terminal domain of pro‑MMP‑9, which may play a role in regulating pro‑MMP‑9 activation.
