    Abstract: Adsorptive media for chromatography, particularly ion-exchange chromatography, derived from a shaped fiber. In certain embodiments, the functionalized shaped fiber presents a fibrillated or ridged structure which greatly increases the surface area of the fibers when compared to ordinary fibers. Also disclosed herein is a method to add surface pendant functional groups that provides cation-exchange or anion-exchange functionality to the high surface area fibers. This pendant functionality is useful for the ion-exchange chromatographic purification of biomolecules, such as monoclonal antibodies (mAbs).

    Abstract: A depth filtration device for the clarification of biological fluids including a composite depth filter media having a nonwoven first layer integral with a second layer containing a polyacrylonitrile (PAN) fibers, a filter aid, and a wet-strength resin. The depth filter media exhibits increased binding capacity for soluble impurities such as DNA and host cell proteins from biological/cell culture feedstreams during secondary clarification and low-level impurity clearance of harvested cell culture fluids, such as those used for the manufacture of monoclonal antibodies. The depth filter media additionally exhibits significantly lower flushing requirements, resulting in lower levels of organic, inorganic and bioburden extractables released, high dirt holding capacities and good chemical and/or radiation resistance.

    Abstract: Chromatography media including a high surface area thermoplastic porous nanofiber and an ion-exchange ligand functionality on the surface of the fiber. The porous nanofibers display a convoluted structure that is comprised of discrete bundles of highly entangled nanofibrils that may be fibrillated or ridged. The porous fibers can be prepared through the extraction of a dissolvable mineral or polymeric porogen that is embedded into the fiber during its manufacture in a melt extrusion process.
