Descrição

Descrição geral

Recombinant, human TIMP-1 expressed in CHO cells. Migrates as a 28 kDa protein under reducing conditions on SDS-PAGE.

Recombinant, human TIMP-1 expressed in CHO cells. Migrates as a ~28 kDa protein by SDS-PAGE. The activation and activity of matrix metalloproteinases (MMPs) are regulated by a family of endogenous inhibitors, tissue inhibitors of metalloproteinase (TIMP). TIMP-1 is a ~28 kDa glycoprotein that is expressed by a variety of cell types. It forms a non-covalent, stoichiometric complex with both latent and active MMPs. TIMP-1 preferentially binds and inhibits MMP-9. TIMPs are capable of altering the metastatic potential of cancer cells and have been shown to inhibit invasion and metastasis in animal models.

TIMPs bind MMPs in a 1:1 stoichiometric ratio, but due to the variable concentration of MMPs in biological samples the optimal amount of TIMP-1 will be assay dependent and should be determined by titration. It is reported that TIMP-1 inhibits 6.7 nM MMP-1 with an IC₅₀ of 1-5 nM (see application references).
