ABSTRACT:
Disclosed and claimed are a method for the purification of polysaccharide-protein conjugate vaccines by ultrafiltration in a saturated solution of ammonium sulfate. The ultrafiltration method of the present invention provides an efficient, readily scalable method for removal of unbound polysaccharides from polysaccharide-protein vaccines, thereby improving the purity and consistency of the polysaccharide-protein vaccines.
