Abstract: The present invention is relates to method for production of a biomolecule adsorbent with a pentadentate ligand with very strong chelating properties, and to methods for use thereof for, for example, protein purification, detection or binding. The biomolecule adsorbent comprises the formula: wherein Q is a carrier, S is a spacer, L is an amide linkage, X is COOH, and n=2 or 3.

Abstract: The invention provides a packing method for high efficiency chromatography columns starting from dry swellable particles, as well as columns packed by the method and the use of the columns in separation of biomolecules. In the packing method, an amount of dry swellable particles sufficient to give a swollen volume in a liquid of about 105-120% of the column chamber volume is transferred to the column, the column is closed and the liquid is provided to the column.

Abstract: The invention relates to a device for separating unwanted compounds from an antibody containing biological sample. The device comprises a porous support and a polymeric resin disposed within the pores of the porous support. The device may further comprise a viral clearance membrane upstream or downstream from the polymeric resin. Methods of use are also provided.

Abstract: The present invention relates to liquid clarification. More closely, the invention relates to beverage clarification, such as reduction of colloidal (not microbial) haze-causing substances in beer or related beverages such as wine, juices, flavorings etc. The method of the invention uses a hydrophilic surface for adsorption of haze-forming substances by hydrogen bonding interaction properties between the surface and the haze-forming substances.

Abstract: The present invention relates to a method for sterilization of different materials, especially sensitive material, such as chromatographic media with sensitive ligands. The method for sterilization of a chromatographic separation medium comprises exposing the separation medium to pressurized steam at a temperature of between about 121° C. and about 135° C.

Abstract: The present invention relates to liquid clarification and stabilization. More closely, the invention relates to both clarification by removal of suspended particles, as well as stabilization against formation of non-microbial haze via reduction of haze forming substances in various liquids. The haze forming substances are proteins and polyphenol tannins which occur in various plant related fluids such as beer wine, juices, flavorings, plant extracts, and even bioprocess streams. The method of the invention accomplishes both size based removal of colloidal non-haze related particles as well as adsorption based removal of haze forming substances without a need for added flocculants. The to method of the invention utilizes hydrophilic surfaces for adsorption of haze forming substances with such surfaces presented by materials arranged in manner so that size based exclusion of suspended particles is also achieved.

Abstract: The present invention relates to a method of sterilizing a chromatography column which is packed with a separation matrix, which method comprises passing a superheated aqueous liquid through the packing of the column to obtain at least one substantially sterile packed chromatography column. The method may also comprise a preceding heating. In the most advantageous embodiment, the superheated aqueous liquid is passed in a substantially uniform flow through the packing of the column, resulting in a sterility of the packed column.
