    摘要: Abnormal infective prion proteins are removed from liquids containing biologically active substances, particularly blood products, by filtration using a depth filter formed of a matrix comprising solid particles of porous material and having a pore size less than 6 microns. Preferably the filter is free of cationic or anionic charged material.

    摘要: The invention relates to methods for the isolation of AAT from solutions containing albumin and AAT using at least two separate metal chelate chromatography steps. The product may be further purified and/or subjected to one or more virus inactivation or reduction steps. The isolated AAT may then be formulated for pharmaceutical use.
