Abstract

The invention is related to a composition of recombinant or transgenic Factor VII, each molecule of Factor VII of the composition exhibiting two N-glycosylation sites, wherein, among all the molecules of FVII of the composition, the rate of Galα1,3G al glycan moieties is comprised between 0 and 4%. The invention is also related to a process for preparing such a composition of FVII.
