Filteration method for cell produced antiviral substances |
摘要 |
This invention affords a filtration method and apparatus for extracting cell produced antiviral substances (CPAS) from a production broth using cross-flow membrane filtration. The broth is perfused into a first filtration cell and caused to cross-flow across an ultrafiltration membrane in the cell, permitting a first filtrate to pass through the membrane consisting essentially of CPAS and some molecular species and retaining in a first ex-filtrate all remaining portions of the broth.
