Abstract
Processes and apparati are provided for separating molecules of interest from a mixture by depth filtration (DF). The DF of the invention is useful in the clarification and processing of various feedstreams for the removal of a molecule of interest. According to a preferred embodiment, a transgenic milk feedstream is stabilized and particulate matter such as fat, casein miscelles and bacteria are removed. An aseptic filtration step was also developed to remove any bacteria remaining in a clarified transgenic milk feedstream.
