Abstract
The present invention relates to a depth filter layer with inorganic layer double hydroxide, a method for production thereof, a filtration device containing this, a method for the separation of at least one contaminant from at least one target product in a liquid medium by means of at least one upstream depth filter layer and the use of the depth filter layer for removal of contaminants. The depth filter layer selectively retains contaminants such as nucleic acids, while target proteins of biotechnological processes are transmissible into the filtrate.
