Abstract: The objective of the present invention is to provide a container for easily and efficiently purifying a target biomolecule from a cell culture liquid or a body fluid and a method for purifying a target biomolecule by using the container. The purification container for a target biomolecule from a cell culture liquid or a body fluid is characterized by comprising an inlet, a filter and an outlet, and further comprising an adsorbent for adsorbing an impurity and/or an aggregating agent for aggregating an impurity, wherein the filter captures the impurity adsorbed on the adsorbent and/or the impurity aggregated by the aggregating agent.

Abstract: A structure includes a water-insoluble fiber, and a low-molecular-weight antibody connected to the water-insoluble fiber. A method of producing a structure includes connecting a water-insoluble fiber and a low-molecular-weight antibody to each other.

Abstract: The objective of the present invention is to provide a method capable of purifying a virus or a virus-like particle easily. The method for purifying a virus or a virus-like particle according to the present invention is characterized in comprising the step of contacting a liquid comprising the virus or the virus-like particle with a water-insoluble inorganic compound, wherein the water-insoluble inorganic compound comprises one or more elements selected from magnesium, calcium and aluminum.

Abstract: The objective of the present invention is to provide a method for efficiently supporting a thiol group-including compound on an insoluble base material. The method for supporting a thiol group-including compound on an insoluble base material according to the present invention is characterized in comprising Step A: treating the thiol group-including compound with a thiol group-including organic reducing agent and an inorganic reducing agent, and Step B: contacting a reaction liquid of said Step A with the insoluble base material.
