Product name:Human MMP9 ELISA Kit
Description:
MMP9, also known as gelatinase B, is a secreted enzyme which degrades the interstitial collagens, types I, II, and III and is produced by normal alveolar macrophages and granulocytes. The expression of MMP9 increases in Epstein-Barr virus infected lymphoma derived cell lines and may be of significance in typically invasive nasopharyngeal carcinomas. MMP9 is constitutively produced by some tumor cell lines (e.g.: HT1080, HL60, U937) but not by most quiescent cells and tissues. Treatment of cells with the phorbol ester TPA stimulates production of MMP9 in some cell types, but the low protein levels produced (pg/ml) often require concentration of cell culture media to visualize the bands by Western blotting.
