METHOD FOR PURIFYING VIRUS-LIKE PARTICLES (VLP)

摘要

The invention relates to a method for purifying compositions containing virus-like particles (VLP), wherein a VLP-containing composition is filtered through a filter medium, in particular through a membrane, having a molecular weight cut off (MWCO) of more than 30 kDa, and the cell culture supernatant of VLP-expressing cells is used as a VLP-containing composition. The invention further relates to a VLP-containing composition which can be produced by this method.
