The present invention relates to a carrier for affinity chromatography comprising an insoluble carrier and antibodies which are modified by activated polyethyleneglycol and immobilized on the insoluble carrier, the antibodies being modified by activated polyethylene glycol at a location other than at an immobilizing site.

Carrier for affinity chromatography immobilized with antibodies

A stirring method comprising placing particles of a magnetic material or particles of a magnetic material coated or covered with a non-magnetic material in an interface between two phases or in a specific layer, and subjecting said particles to influences of a rotating magnetic field to cause rotation and revolution in the particles. According to this method, transfer of substances and/or heat in the interface between the two phases or in the specific layer is promoted. Also disclosed is a stir method comprising placing particles of a magnetic material or particles of a magnetic material coated or covered with a non-magnetic material in a fluid under influences of a rotating magnetic field, to cause rotation and revolution in the particles in the fluid. According to this method, transfer of substances and/or heat in the interface between a phase of the particles and a phase of the fluid is promoted.
