ABSTRACT:
The present invention relates to a method for the purification of alpha-1 proteinase inhibitor (a1PI) from protein fractions. More specifically, the invention relates to an improved method for the purification of alpha-1 proteinase inhibitor (a1PI), wherein the yield of a1PI can be increased by thawing the starting material and incubating it for several hours before subjecting it to a washing step.
