ABSTRACT:
The present invention relates to a method of purifying native, intact fibrinogen from a liquid sample containing contaminants having molecular weights higher and/or lower than that of the fibrinogen. The method comprises subjecting the sample to filtration using one or more filters having a molecular weight cut-off such that the native, intact fibrinogen is separated from the contaminants.
