Název v původním jazyce

An Investigation of interactions of matrix metalloproteinases with collagen by chronopotentiometric stripping analysis

Popis výsledku v původním jazyce

Matrix metalloproteinases (MMPs) represent a family of structurally related zinc-dependent metallopeptidases. MMPs are able to degrade both majority and minority components of extracellular matrix include the native helix of collagen. These enzymes takepart in normal biological processes such as ontogenesis or wound healing but also in inflammatory, generative, and especially malign processes. Zinc ion plays structural and regulatory role in MMPs but it is mainly involved directly in the catalytic hydrolysis of protein substrates. The aim of this work was to propose and optimize the chronopotentiometric stripping analysis (CPSA) in connection with adsorptive transfer technique (AdTS) for MMP-9 detection. The method has been further employed to investigate MMP-9 interaction with collagen. Thanks to AdTS CPSA at hanging mercury drop electrode we were able to measure 5 ul sample volume. We optimized the following parameters: time of the accumulation of the sample on HMDE surface and the
