  • Method for the preparation of sulfated cellulose membranes and sulfated cellulose membranes
    Patent number: 8173021
    Abstract: The present invention relates to methods for the preparation of functionalized sulfated cellulose membranes. In particular, the present invention relates to the preparation of sulfated cellulose membranes under specific reaction conditions allowing to provide a sulfated cellulose membrane useful for pseudo-affinity purification. In another aspect, the present invention relates to the sulfated cellulose membrane itself as well as its use for isolation of proteinaceous compositions. Finally, the present invention provides a method for isolating whole virus, virus proteins or heparin binding molecules comprising the step of affinity purification using the sulfated cellulose membrane according to the present invention.
