Abstract

A method for more selectively removing macromolecules from a plasma solution, whereby plasma containing the macromolecules to be removed is provided and heated to a temperature near or above normal body temperature but below the boiling point of the plasma solution. The heated plasma solution is filtered while at a temperature near or above normal body temperature but below its boiling point with a membrane filter to remove selectively macromolecules from the plasma solution. An apparatus for accomplishing the foregoing is also provided. <IMAGE>
