主权项 1. A method for removing viruses from a liquid composition of recombinant Factor VII comprising one or more Factor VII polypeptides having a concentration in the range of 0.01 to 5 mg/mL, the method comprising subjecting the liquid composition to nanofiltration using a nanofilter having a pore size of 80 nm or less, wherein 50-100% of the Factor VII polypeptides in the composition subjected to the nanofilter are in an activated form (FVIIa) prior to nanofiltration.
