This protein is a member of the TIMP family. The glycoprotein is a natural inhibitor of the matrix metalloproteinases (MMPs), a group of peptidases involved in degradation of the extracellular matrix. It plays a major role in modulating the activity of interstitial collagenase as well as a number of connective tissue metalloendoproteases. Decreased TIMP1 and increased cathepsin V\/L2 levels might play a role in the matrix degradation that is a hallmark of keratoconus corneas. It is able to promote cell proliferation in a wide range of cell types, and may also have an anti-apoptotic function.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePrinciple of the Assay:\u003c\/strong\u003e This kit was based on sandwich enzyme-linked immune-sorbent assay technology. Anti-TIMP-1 polyclonal antibody was pre-coated onto 96-well plates. And the biotin conjugated anti-TIMP-1 polyclonal antibody was used as detection antibodies. The standards, test samples and biotin conjugated detection antibody were added to the wells subsequently, and wash with wash buffer. Avidin-Biotin-Peroxidase Complex was added and unbound conjugates were washed away with wash buffer. TMB substrates were used to visualize HRP enzymatic reaction. TMB was catalyzed by HRP to produce a blue color product that changed into yellow after adding acidic stop solution. The density of yellow is proportional to the TIMP-1 amount of sample captured in plate. Read the O.D. absorbance at 450nm in a microplate reader, and then the concentration of TIMP-1 can be calculated.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eStorage and Expiration:\u003c\/strong\u003e Store at 2-8℃ for 6 months, or at -20℃ for 12 months.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eRange:\u003c\/strong\u003e 31.2 pg\/ml - 2000 pg\/ml\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSensitivity:\u003c\/strong\u003e \u0026lt; 3 pg\/ml","brand":"Biospes","offers":[{"title":"96T","offer_id":47539422331104,"sku":"BEK1209","price":500.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/Biospes-logo_9c5c63b0-5142-4fd1-90d6-cf09cd546c62.jpg?v=1750988891","url":"https:\/\/rndmate.com\/products\/bek1209","provider":"알앤디메이트","version":"1.0","type":"link"}
