Virus filters are membrane-based devices that remove large viruses (eg, retroviruses) and/or
small viruses (eg, parvoviruses) from products by a size exclusion mechanism. In 2002, the …

BACKGROUND : A size‐exclusion filter (Viresolve 180, Millipore Corp.) was tested for its
ability to remove transmissible spongiform encephalopathies prion protein from an immune …

A reversed-phase high-performance liquid chromatographic method is described which

Membrane chromatography is composed of a “filter-like” backbone, such as cellulose
acetate, containing pore sizes larger than conventional chromatography resins. In flow-through …

SystImmune and Sartorius have co-developed a viral removal filtration process for SystImmune’s
