METHOD AND APPARATUS FOR PURIFYING BIOLOGICAL MOLECULES

摘要

In a method and apparatus for purifying biological molecules, especially nucleic acids or proteins, at least one filter (50) is used. At least some of the fluids needed for the operation are pumped in a circuit (51) via the filter (50). First a fluid with biological cells is pumped via the filter (50). The cells retained on the filter are digested. To bind the biological molecules to the filter, binding buffer is pumped in the circuit (51) via the filter (50). A washing buffer for cleaning the biological molecules bound to the filter is pumped via the filter (50), and so the biological molecules bound to the filter are available for further use.
